-Double healer tends to win more often than not.
-Do not be afraid to target tanks. You will find your win rate go up a lot when you do this. They are extremely squishy
-Save your IMP or CC for when a SAM or NIN use ults.
-When enemy team has a warrior or a drg with LB do not stay close to your team, don't be tempted to go in for aoe, heal or use your charge, bait out the stun and then use your charge to move somewhere else.
-When you're healing or range attacking and it is safe to do so, always go in the objective.
-If you have defensive abilities up, always go in the objective and contest it.
-Dragoon and Samurai are deceptively tank.
-Summoner is obnoxious if you let them free harass.
