Episode quests

Ok. Im buying that Episode quest pass. And its my coice, i love it, only its too short. Been only 3rd episode from 4 and im already at last level farming these shards. Dont get me wrong, they are good, but its getting booring at this point. It needs to be a bit longer? Maybe 10-15 more rewards. Just an idea. Or different rewards for these who buy passes. Not 10lvl ahead. Its really fun to get them and makes me wanna play every day.
