Honestly, I've tried the search facility, and I googled this question: When a group of 3 chars, plus 3 mercs finish a heroic task, quite often the last stage is a hail. Should we remove the mercs before the final stage? Would the 3 chars get more XP for the reward without the mercs? Thanks
I remove players and add mercs for final hails. Merc exp is harder to get, and the final hails add a nice chunk of merc exp. Sorry i can't definitively answer your specific question. I suspect there is no adverse effect on task completion exp.
