Ease of leveling all jobs on one character
Music
Environments
Story
Glamour/mounts/minions variety
Fun English localization
The devs really care about the game/community
I enjoy being a mentor despite the system's flaws

Dislike -
No dedicated support role
Savage raids + Alexander in general
Combat jobs are homogenized for the sake of balance
Scripted battles and linear dungeon design
Tired currency and weekly lockouts
Red/blue scrips turned crafting/gathering endgame into tomes for DoL/DoH
Can't optimally gear more than one job/role at a time
Game feels like a glorified chat room because of DF
No reason to go out in the world except for FATEs
FATEs
Not enough midcore content/raids
Cash shop with exclusive items on top of a monthly sub
No Spanish client (yet?)
