>>32235678>Tornadus-TThis thing was broken in gen 5, and Regen was a part of that. The other parts were 121 speed, coverage to choose its counters and no-miss Hurricanes. Since then, weather has been nerfed and speed has continued to creep. The popularity of Rocky Helmet and Dastardly Dolomite makes U-Turning for recovery much easier to handle, especially with LO damage. The creep is too strong for Torn, and even with Regen, it can't keep up.
>ToxapexThis thing is the worst on this list. It does help keep some of the stuff in OU in check, but that is in large part because of its stats, not its ability:
252 Atk Life Orb Bisharp Knock Off (97.5 BP) vs. 252 HP / 252+ Def Ferrothorn: 121-142 (34.3 - 40.3%)
252 Atk Life Orb Bisharp Knock Off (97.5 BP) vs. 252 HP / 252+ Def Toxapex: 109-129 (35.8 - 42.4%)
252 SpA Life Orb Gengar Shadow Ball vs. 252 HP / 252+ SpD Ferrothorn: 110-133 (31.2 - 37.7%)
252 SpA Life Orb Gengar Shadow Ball vs. 252 HP / 252+ SpD Toxapex: 97-114 (31.9 - 37.5%)
If Ferrothorn had access to both recovery and regenerator, I would wager the majority of teams would still run Iron Barbs (at least, when its on a team without other Regenerators) because chip damage is so crucial in this metagame. Back to Tox though: all it can do is Haze, set T. Spikes, or spam Scald and recover. On its own it can be used to shut down some sweepers, but is easily manageable with good teambuilding. Which brings me to the real issue:
>Regenerator coresThis is where it's becomes a problem.
I do disagree with
>>32233651 when it's just about one mon, but on teams that can switch between two mons to heal 1/3 every turn it is a bit too much. Every stall team in OU/UU runs at least 2 regen mons because it's so good.
Personally, I think the only change Regenerator needs is so you are only healed if the Pokemon you switch into does not have the regenerator ability.
This fixes Regen on stall while leaving it as is for most teams.
