more bans per player up the bans from 1 per player to 2, this will ensure that most blatantly OP crap cannot enter the game.
next up, map-specific champ nerfs, junglers like
and
are almost out of control. as for laners
and most other juggernauts can get a hard hit. there are also some other champs whom can be problematic.
then they can increase they map-specific item pool, currently the only interesting item on TT is
which i'd have to go and say is actually OP
then the cancerous HYPER meta should go (funneling on multiple steroids including a CC-immune invulnerable
running your entire team down)
lastly buff the altars, currently having 1 altar is crucial due to the 10% MS buff having the second is not that important tough...
there is probably allot more that must happen to that map, as champs and items are currently mostly balanced around Pro-Play and summoners rift which leaves TT horribly unbalanced.
despite that playing blind pick can still be allot of fun. playing off-meta isn't scolded at, champ select can be very diverse, and assassins tend to under perform due to the strong presence of duelists / bruisers. combat is also very fast-paced but often more decided by individual skill.
lets just hope riot implements an official tournament mode for treeline, this would buff up the popularity which would premit such changes.
