Tower Not Responding To Champions
This is a serious post to Riot.
I just played a game where I went Fizz against a Kayle. The champions aren't what matters here, but this does. Kayle basically went under my tower when her minions were attacking it, which is cool, but then she started auto attacking me and killed me. The problem was, was that the tower wasn't going for her even though she was attacking me under it, it kept going for the minions.
This has happened to me a few times over the years actually where the tower won't target the champion who is diving. It's even happened to me when I was playing, not just other people. I don't think it is lag I never usually lag, and this Kayle was 100% in tower range when she was attacking me. No question about it.
