I know most users do not run a grand master through the game in two weeks, but I do. So here goes. There have been recent updates to street battle XP and Boss XP awarded. I have the last two groups of wizards that have done every side quest, every chamber/instance twice and are now facing the fact that unless they quest Grizzle (which is supposed to be a side quest) they will not reach 50.
What is interesting, I can sit and make cards on Unicorn Way and get the SAME xp that I get beating a boss or some street trash in DS. I am not sure when this update occurred. Before the October update, I could bring a noob into a fight with Vika (Crystal Grove) and always get it 50 xp just for being there. But, this change of course just makes users last a little longer huh? Oh oh silly of me.
