This sounds like a great forum challenge to me! We have our hero guides for builds and things (hint hint, all, please feel free to add to them), but we could use some collective threads on rotations, wave management, map control, and all those other intermediate/advanced concepts.
For instance, a new generation of threads like this: Know your rotations! How to execute rotations correctly and what to watch out for could be great for 5v5. I’m more than willing to help folks if they need graphics to illustrate their words!
Let me think on how best to organize this, but I think we can do it in a fun way that doesn’t require too much effort on any individual person.
