In other games, I love the freedom of Bethesda games and all who are similar; I want to vary how I play and what I play and discover something new whenever I get bored. In 14 I love being able to switch jobs at will; in my ideal world there'd be no jobs at all and I'd pick and choose freely from all the skills and set my own stats, but that's not happening, and that's okay too.

In fantasy settings, I usually play a mage (bonus points if I can summon things) or dual-wield swords, and I want full immersion and personal roleplay potential for my characters. In 14, I'm primarily a Black Mage, Summoner, Ninja and a Dark Knight (which for story/roleplay purposes I pretend is a pure mage, but I do enjoy the gameplay a lot), and I'm super looking forward to Viper. I loved Rogue, wasn't as happy with the switch to Ninja and just wanted an advanced Rogue back, and Viper has the potential to be what I was looking for all along.

In single-player games, I also like to get creative with magic, mess around with different spells and playstyles; 14 is a lot more strict about what skills to use and what job is like what. Speaks to how much I love the game in general that I take that compromise and restriction lol. And in general in RPGs, I like to be tanky by stats because I don't like to defend and be cautious; I prefer to throw myself in the thick of things and self-heal if necessary. 14 is set in its trinity of roles, but when I'm solo questing, I'm often on Dark Knight out of my favourite jobs because then I have to worry less about health.
In the only other MMO I play (ESO) I've been primarily a healer for a long time and gave it a try in 14, but it's not for me here - too busy, too squishy for so much responsibility; its just not my playstyle.
