>>25039668The only mon that could get Ice STAB without actually being an Ice type (that is, no SE weakness). It was great during the XY meta, but ORAS pushed it over the top since the tutors gave it other moves to beat the counters and checks it has in XY (most notably Gunk Shot and Low Kick).
>>25039646If you treat it as 1 vs 1, then yes, Greninja is not bonkers. But that's where the rest of the team comes into play. Ice Beam and Dark Pulse are essentially the only two mandatory moves since they have such great offensive coverage, leaving the last two slots open to beat its usual enemies. Yes, it can't cover all of them even with its new moves, but a player CAN design its team so that the counters to their particular Greninja set is handled by other team members, while other walls who think they are safe can be beaten with Greninja's coverage moves.
So basically, Greninja was arguably the best cleaner there was. Excellent speed tier, STAB on everything, which coupled with Life Orb actually hit surprisingly hard despite not having fanastic offensive stats.
Either way, just play Battle Spot and VGC if you want to use it so badly. Being banned to Uber is essentially the best compliment a Pokemon can get.
