trexx has been good in stage 2, but I think his performance in split 1 was average at best, he's definitely an integral part of the team, it's just that as a team VIT has played every map win close, (with very few exceptions) and I just don't think its sustainable to keep it up with Cender's style of calling.
Personally I haven't really seen any threads calling for VIT to blow it up, but I have seen a few comments here and there, but there's always such comments for every team. I think they should continue with their current roster into the off season and see if they can get any upgrades for Kicks + RunneR later on.
