Good thread! I like these types of topics.

RPG is such a broad term that I have different preferences depending on the type of RPG i'm playing and what genre it's crossed with.

For 'rpgs' like League of Legends, I generally used to play simple characters like Rammus/Udyr/Nasus (sometimes Kha'zix) though. Usually characters that do well on their own. That said, I love supporting my team mates and protecting/helping them (hence the junglers)

For D&D style of crpgs, I'm almost always a paladin type character, that can support but also bring the heat when needed. Morally good characters appeal to me in crpgs.

Action RPGs like Diablo, I love pet/summoner classes, lots of fun having a little army killing things for me.

mmos make me anxious, so I usually stick to DPS classes, hence Summoner and now Reaper being my two highest levelled jobs currently.
