ATM I always have a runepage for general ADC's, Junglers etc. but not for specific champions, does it make a big difference if you play with general runes or runes for every specific champion? I mean do you have big disadvantages that matter, or should I only take the afford for ranked games?
Would be great if an experienced player could give some feedback on this :)
Unless you're trying out a very unique and special build, rune pages for a specific role are often very similar. For example, most ADC's want attack damage or armor penetration, armor, magic resistance (per level) and either more attack damage, more armor penetration, or attack speed. Which of the choices you pick depends more on your preferences and play style, as they are all viable for most ADC's. Ideally, you'd want a specialised rune page for each group of champions, but if you're short on IP or rune pages, this makes too little of a difference to matter.
If you're mainly playing a single role and have several champions available for it, creating several rune pages for that role and just one generic page for each other role you can play is your best bet. That way, you can diversify within your role, but keep the flexibility to play any role. This again depends on the number of rune pages and runes you have in the first place. The flexibility is much more important than the diversity within one role. It's better to be able to play whatever role your team needs well than to play only one role perfectly.
But you really don't need a page per champion. Actually, if you start making them, you will notice that the differences are sometimes simply not there and sometimes negligible. You might also notice that different people and guides use different rune pages for the same reasons. That also shows it's more or less irrelevant which approach you take and you can very well use only one rune page for several or all champions fulfilling a specific role.
Generally, rune pages can be shared by multiple champions. There are times though where rune pages can be extremely effective when they are made for a specific champion.
Standard AD Page: AD Marks, Armor Seals, MR Glyphs, AD Quints/Lifesteal
Ezreal AD Page: AD Marks, Armor Seals, Mixing MR Glyphs with Mana Regen, AD Quints
Standard AD Jungler: AD Marks, Armor Seals, Scaling MR Glyphs, AD Quints
Nocturne Jungler: AS Marks, Armor Seals, Scaling MR, AS quints
Standard AP Tank Top: Hybrid Marks, Armor Seals, MR Glyphs, AD/AP Quints
Mundo Top: Hybrid Marks, Armor Seals, MR Glyphs, HP/5 Quints
Ryze Top: Hybrid Marks, Armor Seals, Mana Glyphs, Mana Quints
Notice that a the standard pages, multiple champions can use. Some champions work very well with specific rune pages though which gives them a nice advantage in lane.
Ezreal tends to be very poke heavy and can run out of mana fairly quickly if you poke hard. Adding some Mana regen in place of some MR can win you the lane by letting your extra poke whittle down the enemy forcing them to either play defensive or potentially die.
Many junglers like Pantheon or VI build straight AD for damage from abilities. Some junglers synergize very well with the new Feral Flare or do more damage overall the faster they attack and so instead of damage building lots of attack speed greatly increases their damage output.
Many top laners will have pretty similar builds. Some tanky ones like Malphite or Shen might run those standard pages I show up top. Other tanks like Mundo don't benefit from the same. Mundo tends to farm with his cleaver which constantly drains his HP. He needs the extra health regen quints to safely farm from afar to keep his HP up. Ryze gets a huge bonus from having extra mana to damage. Level 1, if you have all mana Glphys/Quints can get his level 1 spell damage to 109. This is pretty significant.
Basically, you don't NEED to have additional rune pages. You can get away with having 2-5 but if you are vs a similarly skilled player, your better runes could give you the edge to win the match and potentially snowball your lane. Currently, I run 19 rune pages for a variety of champions.
Having a perfect, specialized set of runes can sometimes give you a tiny advantage in a lane/game. However, the lane/game is overwhelmingly determined by your skill with the individual champion first, and champion matchups second. Runes are a tertiary factor at best, and it requires a pretty high skill level for this to really be a relevant issue.
Therefore, you can get by for a long time with generic runes on the vast majority of champions. If you have a lot of IP sitting around, you can spend some time thinking about idealized runes and whatnot, but if you don't have the IP, I wouldn't spend much time worrying about it. Even in, say, platinum level play, you don't need that many rune pages.
You can get away with 5 pages minimum (basically one for each role), but having about 7 is a slightly safer number (to cover the possibility of facing an AD mid or an AP heavy top). From there you can build specialized pages for specific champions.
I know this thread has been answered already but still, my view on this... Some champions can share rune pages like described above. However, some champions require a personal rune page depending on how you play that champion. For myself, I have a special rune page (and masterie page) for my Ezreal. I play Ezreal like noone plays him, but it works for me. I play it with AD quints, AD marks, flat health seals and CDR glyphs. This gives me 10% CDR but then I would have no magic resistance. Therefore I replaced the nerfed armor seals with flat health. For me, this is the perfect balance, but it's a pretty weak start build.
It all depends on how you play basically. Some people like to have AD marks on mages mid to be able to last hit better and to have a bit more harass early game in laning phase, but not everyone likes that.
So basically: you should stick with a few champions and master them so you know whether to use specific rune pages or not :).
