Simple suggestion for infection. When you are playing in a 1.9 or 1.10 client there are some places on maps that you can't reach or pass because of the collision boxes are enabled. My suggestion is to disable them (simple as that).
Well.. there are some reasons why some people use 1.10 and it's annoying to have to change the client in addition to the other problems on infection.
It is annoying to have to keep switching clients to play on one server that is 1.10 and then Mineverse which is best on 1.8.9.
Support! Personally I don't use 1.9+, but I can see how this can be frustrating for players who do use 1.9+.
Agreed, a lot of people couldn't make it down the ladders on winter or whatever. They all got SLAUGHTERED. Support
