I'll be real with you for a sec.

Back during I think 3.0 when we got Han and Roshi treasures, sometime after its been awhile since their release (I say about 6 months), I managed to have both Han and Roshi (didn't start on Roshi til Han was released) and I was running around with my 4* Sailor Sakura (could get nearly half her frags for free from mission mobilization event which I only spent around 2k coupons on her and got her to 4* for how cheap she was to me) and me running water main, I was called P2W in arena just for running Han, Roshi, Sailor Sakura.

Meanwhile when I was running my Hokage Minato sometime much later, no one ever called me P2W.

People just be mad and want to create excuses for losing instead of improving themselves.
