yes change name are allowed
yes we have backup player that are eager to play!!

then they should discuss and change roles, i believe most of them are quite flexible, they all do have different playstyle, but warding is important to avoid ganking, some people can play without ward because it is simple, mini map is there, we do notice in mini map and check whether hero missing from the lane and so on,sometimes ppl will forgot to report

yes, all of us would prefer multiple style and change depending on situation, but once we are on that role, we must utilize that role also

sometimes i do see supporter ks creep and heroes when with carry also

   

For some reason i'd love it.

now much2 more annoying hero are nerf and now can work out new strategic pick and ban
