4/1/2 5* Iron Man

My five star IM is now 4/1/2. I’ve yet to level him up but could get him to level 360. Right now his red at 4 covers does 2040 + 1646 for each team IM ally. Yellow countdowns do 1403 at two covers.
Does anyone know what the power of these would increase to if I leveled him tolevel 360? It’d cost about 250k ISO, all that I have.
We really do need a way to preview the effect of leveling up characters. In instances like this I have no idea if using all of my ISO would even be worth it, especially considering the effect it’d have on who I would fight in PvP and the fact that my only championed 4* is Hulkbuster, who would either now become irrelevant or still be more powerful than 5* IM at level 360 and I’d have been better off using that ISO elsewhere.

Thanks for any info!

General rule of thumb: only start leveling 5*s when they have 10 covers or more.

Exception, as always, OML.
That one is useable at 1/2/1.

All others simply aren’t worth the raise in scaling unless you have at least 10 covers.
