Starting on light foot I was having fun with my rogue in smugglers rest, I thought finally something for my rogue to enjoy other than risa. Then went into crystal cove and ???? Undead. Of, course after a day I was denied into parties and why not? just need some wizards, cleric, and a tank and you have it. So I do what I always do for events and grinding (orchard tapestry's, sands bloodstone) switch to wizard and play. Now before anybody says buy a +5 greater undead bane, they are very hard to find and very expensive still for the moment to buy. Green steel crafting is a option with greater disruption but have some minII, rad, and HP items to get out of the way first and this will take a long while.
So devs I'm not for sure what to say about how to balance the game with the undead but if you put them in the events rogue characters are just left out.
