Wouldn’t the simple solution to the respec problem be removing the power cap? You can increase max level, or have it remain static for covers 14 and 15 if you don’t want to widen the gap between 2 and 3 ability characters.
Seems alot easier than trying to work a respec function into the game and all the ancillary issues that would need to be addressed.
Giving folks the chance to differentiate their heroes is really important to us. Half of the theorycrafting that goes on is about working out what the best ability distribution for you is going to be.
When the game first started ( September / October ) the power cap was 20. Now it’s thirteen.
It was 50 (out of 60, 20 each per ability). You’d get one ISO level for every cover you found.
Don’t remove the power cap but absolutely highlight it and explain it to players better.
If I hadn’t come to the forums I doubt I would have realised the importance in cover selection for a long time.
You know what I meant by 20, 20 per power or something. 
I guess there is strategy involved in deciding an optimal loadout for your playign style, and it does foster healthy discussion in the forums, but the power cap leaves me very unsatisfied knowing there are 15 possible covers and I can only achieve 13 of them.
I’m stuck with a 3/5/5 Thor, and those two extra red AP to kick off mjolinir might are irritating the hell out of me. Expanded roster to accomodate a Thor 2.0 rebuild, although might end up getting kiboshed before I can finish collecting covers after inevitable nerfing. Hope it’s not too drastic, I like the idea of having two Thor’s in circulation so I can rotate them in and out of battles.
