Hmm, never though this thread get this long, and have lots of known player and forumer i know or have interact with; reply with arguments and facts about 'immortal team'. Me, been using the setup but now i use blitz team instead for obvious reason (fast fight, can be used on many type ingame like ti, sw, 9tails, etc). Long story short, people tend to use (or mimic) team with the highest winrate (kudos to Kitai Suru for pointing this out) and yeah, much easier to be a follower then the leader .. until new and better tactic and teams comes out (Germany got the 3.0 update already so head ups).
Like my old m*ways says to me : enjoy it while it last, or just endure it ;p
