I'm going to bump this thread again.
I don't care how it gets done, I just want to see a change in the EXP system.  I will probably stop playing again after I retire this gen.  It's just not fun.  I am at a 1x multiplier almost all the time.  I have roughly 22 1/2 hours to level 31, and that's assuming I keep a 2x all the time.  Even with a 3x that time is still 15 hours.  That's a long time, considering I am playing a game.  It actually looks more like a job, 30 hour work week is about what I do now.
Yes, I understand that the game isn't completely about EXP.  Removing that from the equation for a moment, the game still has problems.  I think I would be more inclined to grind if teams were more balanced.  One of the big problems I have with this game is that team balanced mostly seems extremely one sided.  The system actually REWARDS team stacking, something I have a big problem with.
Stop rewarding the team so much and reward the player more.  This is the first step.  Put me in control of my progression.
Team balancing is a bit trickier and I'm not sure how to address that.  It's not like we have a matchmaking system in place.
So, I would like to see the EXP system reevaluated to be more player centric, as opposed to team centric.  Even more so, I think players would be more apt to grind if it didn't feel so unforgiving.  Nothing more demotivating than being stuck at 1x with a team that keeps getting rolled.  I've got better uses for time, especially when I'm looking at 20+ hours of that crap.  It's more work than fun at that point.
I would also like to point out that DTV is more profitable than playing Battle, at least for me.  Does that seem wrong to anyone else?
