I would like some horizontal progression, but it won't work in this game for 2 reasons:
1. can't change gear in combat
2. there's only 1 tactic for every fight, DPS

Because of enrage timers, every fight is a dps race. So every gear build comes down to what gives you max dps. Kiting, enfeebling, and other tactics that worked in ffxi don't work in this game. With that in mind, I'd like more options for obtaining gear. Right now you can raid or you can tome grind.
