When you sit down to a table, who are you always glad to see? This could be a character build, or something to do with the player themself. I'm partial to evangelist clerics myself; not to mention people who bring multiple character sheets to provide the group flexibility
I try to avoid favoritism at the table as any good GM should. I DO enjoy when a player or players come up with a particularly creative solution to the problem at hand. I really enjoy when they think of solutions that I had not considered.
