My personal opinion is you remove Mental's Digital weakness, keep Mental's Electric weakness, meaningfully buff Earths in general (not named Vulffy), specifically give Earths synergy/teambuilding options that makes it better to put them on the same team as Mentals, and buff some of the Digital tem statlines to compensate a little. I think removing Digital is the least risky/easiest to manage. I think removing Electric significantly buffs the type and significantly removes the problems the type has when it comes to teambuilding. It does immediately fix a lot of stacked type weaknesses for the dual types and makes pure types more reliableĪlso not double checked but it gives a general idea.)
With that I think there are two routes I'd take, and it bleeds into small buffs/adjustments into other types that a good chunk of people think need some help anyway.ġ) If Electric weakness is removed, existing Mentals will need to be tuned (possibly even nerfed) to account for this, but all other Mentals (pending Arbury) will probably be significantly more easy to justify on a team.
You basically can't compensate for Mental as a type, because there is almost always some notable common weakness (like water) or some really ugly x4 weakness. Every mental dual type has a minimum of 3 weaknesses.
