Han is 210 Seals at max.

Sailor is practically free at this point if you've played long enough.

Mei is the only one that's reasonably hard to obtain as it depends on your luck. Can be 60 seals to 1k.

How is that "P2W"?

A number of complaints stem from lack of experience or generally how to counter basic setups. Just copying and pasting a team you get here won't help if you don't know how to manage skills and resources to best suit you.

Why play competitively if you're gonna complain at every "Paid" ninja you spot?

It's frankly irresponsible and I'm completely dumbfounded that there are people that consistently whine like this.
