>>22283270Lando-t is perhaps as centralizing as Gren, but it has more reliable counters. Thundurus, as well, since every time you use a setup sweeper, you have to think,"Fuck, what if my opponent has a Thundurus?"
Greninja is also not too hard to take out and unlikely to destroy an entire team by itself. It may not have many (any?) hard counters, but it lacks OHKO power unless it can hit everything for SE damage on the weaker defensive stat. Not to mention it's weak to priority, easy enough to revenge kill, has no boosting moves, and dies after one good hit.
I don't know if it's worthy of being banned, but I do know that most people who comment on this subject are fucking retarded. On that ground alone I'd say leave Greninja be. We shouldn't just ban whatever a bunch of dumb cunts have decided to whine about this week.
