What is up with the Dimensional Rift? Is there some secret? We did it, full party... we did the Level 60+ one, and we were transported to 3 rooms twice each, mobs were low xp, drops were nothing to speak of... and then it was over... The only thing I'm thinking is that we did have 1 or 2 in the party that were in the high 50s. Does this make a difference to get rooms that are challenging and drop stuff worth your while?
we did the 40+ rooms at level 47, 5 of us. healer,buffer,tank,nuker,dd and did quite well. each trip in we came out with 10-20% more exp than we started with, even accounting for deaths. we also had some ok drops, lots of 4-6 piece mat drops, some enchant scrolls, nice adena drops, etc
then, when we hit 49 and 50 we did the same run and were very dissappointed, so yeah, i think that the level may have much to do with it. We did the 50 rooms and were making bank again, but being at the bottom of that level range there were rooms we just couldn't hold due to the aoe mobs
