>>21703860There are several facts that stop it being "acceptable" since Gen3.
If you mix all of those together the scenario is even more catastrophic.
- poor base speed stat
- poor movepool
- type
Even if Flareon got Cotton Guard (for stallish and BP sets, even if Vaporeon and Scolipede are better), Crunch and Wild Charge it would be still bad.
You can't change its base stats that are the premier factor that ruin its dreams of being an offensive threat.
I personally still prefer it as special wall with Wish and Lava Plume and fillers, even with this role Flareon is still outclassed.
Only a mega evolution can save it, but it would require a significative Speed buff and Attack one, the rest all in Defense. But then it would still be a mediocre if not bad mega with a serious movepool issues.
