DRG is fine where it is, yes sky high needs to be addressed (trust me I know the pain of hitting that button thinking I'm fine only to just die because of DOTs...) but you can still work with it. You basically need to play on the edge of fights and only go in when you need to or to get a quick burst off. The majority of your damage should be coming from your burst combos. Gskogul>Wyrm>Nastrond. That's a 20 to 28k burst in about 1 second your other is High Jump>Gskogul>Chaotic Spring>Horrid Roar(If up) Nastrond>Heavens Thrust with Elusive jump to get out of a situation and a Wyrm to follow up anyone who is low or running away. If in a big battle use guard after a burst combo to see who's low on MP or HP and to let your skills come off cooldown then get back in it or out of it. Always try to use gksogul into sky high OR bait the guards out of your enemy with a sky high and immediately come down when you can and use Gskogul, elusive jump into wyrm and nastrond that will do a nice chunk to all the enemies there which can give your team the killing blows. BLMs and BRDs are our worst enemies seek them out from playing behind the enemy team to harass or avoid them. DRGs can be pretty versatile you just gotta pick your fights and when not.
