2* vs 3* Daken and Wolverine

I’ve champed both Daken and Wolverine, so I’ve acquired the 3* covers. Is there enough difference that I need the 3* versions? Or would my Iso 8 be better utilized on other 3* characters?

Those two were my go-to PvE grinding team for quite a while, you can’t go wrong with true healers.
3* Daken is pretty much a carbon copy of his 2* version, but he gets more powerful at higher levels obviously. Patch is a lot better than 2* Wolverine though - Patch heals automatically just like Daken.
In short, I recommend trying to roster both.
