When should I disrupt an opponent's recall?

Question

In League of Legends, I can interrupt an opponent's recall by damaging them with a spell or autoattack, but what I'm not sure of is when it's appropriate to disrupt them.

For example, if my lane opponent is recalling and I can easily disrupt him, should I do so and keep harassing him or let him go to buy items in return for some uninterrupted CS? Or if the enemy jungler is recalling in a warded bush, should I interrupt him to keep tabs on where he is?

Answer 1

The answer to this is really simple, ask yourself the following question :
"Do I get a benefit from interrupting him ?"
- if yes do it !
- else don't !

For your lane opponent, if he just hard pushed the lane and you see him back, prevent him from doing it ! Because if he does recall, he'll barely lose any cs so make him lose time for you to prepare the push for when he is gone.

Other case, if he wants to recall because he is out of sustain (pots, flask, low health) or because he is behind in items and need to shop, PREVENT THE RECALL. You have an advantage on the lane, don't let it go.

If he is too far, and you need to overextend or lose cs, ask yourself the same question again, does it still gives you a benefit to do it ?

And for the jungler, if he is backing on a ward he doesn't know about, it might not be a good thing to prevent the recall and give the information that it is warded there, because when he comes back to your lane, he will know what to avoid. But if he is doing a stupid back in a visible place, go for it.

Answer 2

For tactical reasons: Don't disrupt the Jungler. If he doesn't know you know where he is and where the wards are, you have the upper hand.

However, you see an opponent in-lane, open fire. That's a very big generalization, because there are a lot of tactics and different situations you might need to take into account.

LoL is very much a Mind-Game as much as anything else.
