I used the Mining Guild set with my ranger for quite awhile (one of the level 15 sets you start with in the Steam version and North American Xbox version), but other than that just used random, unique and purchased equipment. I did collect set pieces, though, and saved to try out a couple of them (reloading being easier than re-equipping all the original equipment).
I'm using the Orobas set right now, but I actually could have better melee and magic resistance (with admittedly-lower ranged resistance) by switching to some great generic gear I've found. I just happen to like how it looks. I might consider using the Aleroth Archmage set for that reason, but it will take so long to get it that I wonder how much I'd be sacrificing in the meantime.
I just edited in another question to my previous post right after you posted your response. Do you happen to know the answer to that?
By the way, thanks to you and Stabbey for the help.
