The last two roulettes I have run, the other DPS (both of them melee) are sitting at full TP, and single targetting mobs when there have been 10+ mobs on the tank. Furthermore, I am bottomed out, with Invigorate on CD and no Goad, even though I politely asked for it.
Please guys, when there are 4 or more mobs, it's just better to use your job's AoE skills. You're contributing only a tiny fraction of the damage, as a DPS class, if you're single targeting during big pulls.
In addition to this, take the TP regen utility skill (Goad & Tactician) if you're a physical DPS and the other player is also a physical. Keep an eye on their TP bar during big pulls, and use the skill when they are at about 50% TP.
Every job has AoE skills. Please use them.
