Heya Steel.  Wife and I are playing 3 accounts atm.  So with mercs we are a full group and plowing stuff up to planes.  We did some of the higher stuff but mostly we are doing AA and levelling slowly.  Tonight we will ding 69 and 780 or so AA.  We are enjoying the game in going back to old content and reliving some fun places we went to.  We havent done any raiding or grouping with others.  Some of that happens on the weekends with a few of the open raid groups though.  I would say grouping is tough until the 80s.  With mercs most people just seem to solo or box.  The game is definately different now though.  The armor and weapon changes along with AAs have my head spinning but I am learning.  So many options for gear that I can't make up my mind what to do.

If you want Euro though I would definately check each server to see where they are.
