So… we mostly agree that the ISO crunch is a real beast to deal with.
Most of us also probably have multiple characters we almost never use.
Why not help encourage roster diversity AND make the climb to Champion a little less steep at the same time? Not to mention make each fight worth just a little more.
I would like to see characters gain XP & level up from actual play. Yes, I realize we get a little ISO for each fight, but that’s probably going straight to some character we are trying to take to max level. It doesn’t have to be a ton… in PVP, for example, each player on the team might get XP equal to 2x whatever the match was worth in points. So if you used the same 3 over the course of a PVP and finished up at 1,000, but got hit a few times, each character would along the way gain an extra 2500 XP or so. Only 1 level (or less) for a high-level 4*, but enough to get a low 3* or 2* multiple levels. You could have a similar bonus on the PVEs… 0 - 150 XP per fight depending on the level of the goons.
I realize that the problem with this is that some people don’t want to take certain characters up. But D3 seems to be wanting to push people away from soft-capping, and there’s a decent chance the recent damage changes have already messed that up for you anyway. Or maybe at the rewards screen you could decline the XP.
Regardless, I think it would be a positive addition.
