Should have banned bristleback in the tourney....

Anyway my suggestion for sentinel if you want to play farming first

Tiny
SA
Sniper
(For farming late game)
Lina & CM (For offensive purpose)

Or you want play killing team can choose this one maybe

Shaman, Moon, Lina, CM and Zeus

Early game GG people fast.... if not late game you can straight give up-- no need waste time
