Well let'see i like playing more of a tank role but i don't mind a caster but it has to have a certain feel for me to consider playing one lol .
In dark age of camelot I played a Friar on Lancelot , A necromancer as well both were fun classes cause for the firar i could pretyt much do it heal when i needed to the buffs were very nice and overall friars were a tough class to play against if you played your friar right and pending on the spec it was , As for the necromancer i found it a bit fun because it was easy to pl and farm stuff

.
Now Hibernia was my realm for many reasons . I played a chanter and while it was more difficult to play it it made great in grp for keep and tower defense and also for a pure hib bomb grp . The tank classes i could never really try to get one down maybe because of the game mechanics and such but the warden and hero classes i really wanted to try .
And finally my all time fav class in daoc completely was the eldritch , I had a 46 Light 28 mana spec eldy and the dps was great but i also, had alot of utility from a decent mez and aoe disease and great nearsight and stunn , Most of my rvr time was on the eldy and i really miss playing it lol .
But what i liked about wow was playing a warrior tank and pally tank as well
I guess what matters for me for each mmo is the fun factor if i ain't having with the tnaking style ine one game but like the casteing more then it is simple i'll play a caster role and vice versa with tnaking , Each game is different for me overall in terms of whct classes i will play .
