Something needs to be done about this. At the rate I'm going, my merc is not going to get more then 3 AAs banked. It just went from 100% to minus 57%.
From what I can tell so far, it seems that my Merc is totally bugged and stuck (as mentioned above and elsewhere) if my EXP bar is set to normal EXP only, which normally shouldn't matter. If I set it to 100% AA EXP then my Merc seems to become un-bugged and starts gaining EXP but at a majorly reduced rate. Sure, it seems to be moving now but will be ages before I get 1 Merc AA!!
Dont forget the Merc AA bug.. i cant get exp with merc (100Exp)@Main, set it than 90Exp/10AA , now i get again exp my alt so far ok by 100%. ) steps: 0,xx/0,78/1,14 (1 AA Banked)/1,37/1,60 > next step0 >>>>>Than my AA exp bar goes 0,0 > ZERO. Hope Daybreak bring back the lost Merc AA, hard enough to do that exp.
Merc AAs need to be tweaked anyway. it shouldn't take so long to get them and is just another pointless roadblock that adds to the tedium of the game.
