Another 3* champ or a 4* bump?

https://mpq.gamependium.com/rosters/Punter/

31 of 40 3* champs (Switch and Cyc need covers and will be champed when I can)

I’ve about 100K “spare” ISO in my budget right now

Do I spend it to bump up any the following remaining 3* to champ, all have covers in my queue - Squirrel, Colossus, QS, Doc Ock, keeping on my all champed 3* quest

Or

Do I bump up XWolv and Nick F to lvl 188? Currently only of my 4* that are close to usable. I have Leg tokens, but not the roster space for new Chars so not opening. This would also officially mark the day I move off ISO on 3* and into 4* focus.

No need to rush into 4-star land, keep building your threestars until you have a worthwhile fourstar to level (Wolverine and Nick Fury do not qualify).
Squirrel Girl and Colossus covers are handed out as rewards this week, so that might be a good place to start.

You are close to having all the 3* champed. If you can resist the urge to open the LT you probably should focus on that (plus the full 2* farm if you can). Eventually you will see big increase in rewards from champing 2 and 3* and you will have enough HP and Iso to move gradually to 4*.

Actually the patience required to do it is commendable. Well done.

Yes patience is right. Learned early on that wasting ISO on cover-low characters was not the correct way to play this game.

Hence why I’ve focused on the 3* characters which are mostly covered after a long time of playing. Now that I’m over 75% of the way through them getting champed though with only the low-tier remaining my patience is wavering!

What’s stopping me opening more Legendaries is my lack of HP, don’t want a new 4* I can’t roster.

I did some more math with ISO requirements on setting up my 2* farm, plus Cyc and Switch champing, not quite as ISO rich as I thought so I’m holding off on spending ISO just now on the remaining 3*.
