Sparton and team - it appears that lots of players are hitting the stack limits for XP and evo shards with these LoL events. At best, this leads to sub-optimal use of these materials (even selling them in some cases). At worst, it leads to MACLx errors.
Would you please consider increasing the number of allowable stacks? Would you also please consider adjusting the tuning of LoL drops to emphasize 5* XP shards more? You could keep the average amount of XPs in the drops constant, but just allocate them more heavily towards 5* (and even 4*) shards. That would allow us to store more XPs per stack. Thanks!
