I'm curious, I wonder what the reasoning is behind the 2 hour cooldown before you can switch a support to another character. I've been thinking about it and haven't come up with any ideas that I find truly satisfying. I'm not trying to be confrontational - I don't care about the cooldown much one way or the other, but I wonder what the rationale is.
An answer from a red name would be welcome, of course, but I don't really expect one - it's a minor question and we ask them a lot of questions. I invite anyone who has a good guess to weigh in.
