I thought the funnest parts about sacred 2 were: 1 beautiful scenary - i know it's all relative but I enjoyed the visuals 2 fun multiplayer crowd - good friends, not too much aholes and very helpful people because no 'wealth' 3 fun to create builds
Regarding builds the TQ dualmastery was pretty cool but as we see from Poinas guide to skills there is something to be desired in terms of variation in builds. It seemed like Sacred 2 took more creativity. No respec could be looked at as a pain, but considering my 3 enjoyments it didn't seem a problem to re-roll a new toon all excited to try a new concept.
Oh another thing I liked about sacred 2 is the little things they did such as the humor. "it wasn't that great being a skeleton anyways" as the bones make a satisfying crunch
