To max or not max 4 star?

I have been leveling all my 4 stars evenly to prevent issues with scaling on pvp and pve. Currently all 4* are at 170. With new champions out now I want to start maxing them but am not sure if I max 1 or 2 4 stars what it will do to my scaling. Any thoughts? I can max 2 4* with iso reserves but then it will be months before I can level anymore. Is it worth it or do I just continue leveling evenly?

You could always adopt my previous 3* strategy and just devote all ISO into the one or two boosted 4*s you own for that week and then stop when they’re no longer boosted.

Well, the recent vague “changes to mid-level character power levels” apparently weakened some 4* around that level, damage-wise, so once you champ your desirable 166s (and basically all of them are, because then 1 cover = 1 LT), you might want to pick 2 4-stars to max.

I wish I had written down my power damage before the change, but my 210’s powers do about 10% less than they used to.
