I like ranged classes, so mages or ranger type classes, that being said though, I hate casting times, so I do tend to lean more towards ranger classes. Whilst I do experiment with melee classes sometimes, I always end up overextending and getting myself killed. I wish that I got better at melee classes though, because in games with equipment customisation, heavy armour tends to look the coolest. As for healers, tanks or stealth-focused melee classes, never really been my thing. I like doing the deeps.
Examples:
In WoW I mained a Hunter.
In LoL I tended to play as Varus.
In GW2 I mained a Warrior, but I always had a rifle as my secondary.
In all 3 Dragon Age games I played a mage.
In Skyrim I played a archer/sneak combo because it was OP.
