So I was wondering, after watching some LCS games, I normally place anywhere from 28-36 wards in a 45 minute game when I'm support. Should that number be higher? These guys in the pros are placing like 80-90 wards in their games, but since I'm in low ELO (B3), I definitely don't have to place as many as they do. What would be a good amount of wards in say a 45 minute game?
Vision is highly important, no question. But the lower you are, the less important it becomes. From my experience, people in B3 are far too focused on their lanes and do not pay attention to the wards placed around them. I saw a lot of times that the jungler was obviously running past a ward to gank and the laner did not notice it.
Don't make sure that you place ENOUGH wards, placed the correct ones. If you ward all important spots and placed during the game correctly, 28 - 36 wards are completely fine.
Also, you have to remember, LCS is different from SoloQ. On my elo (D2), the players place ~ 50 - 60 wards each game, so well ... kinda embarrassing if you only check the numbers. But the wards are placed at the correct spots and are more than sufficient.
Don't compare yourself (especially B3) to LCS players. They are in constant communication and have game plans laid out already. Vision is directly tied to their game plans and such.
A good support wards keep your ADC safe. You have to ward as much as this is needed. If the enemy support / jungler is spending resources to kill your wards, you have to spend more resources to get more wards. If they are keeping your wards up, you are free to do other things.
There is no good number to go by. It's a stat that is misleading. It's all about keeping vision on the enemy, their objectives, dragon and baron. You need to play each game on a play-by-play basis. If your ADC is getting fed, you may have more resources to ward the enemy jungle. This will inflate how many wards placed for that game.
Ward is an awesome item and people think the more wards the better. But the thing is that a well-placed ward worth 5 dumb-placed wards. Your wards should be placed where the jungler is most likely to go to your current lane. And, you're just a B3, so you shouldn't stick on placing wards all over the place. LCS is a whole different level, the opponents are unpredictable, that's why they need wards - to control the map. With your current level, you just need 20-40 wards per 45 minutes. Also, your teamates can place wards too, right?
