4 primal (Hard) runs just today, and 4 lots of loot taken away from the person we were helping. Why? Grand Company seals and synthesizing. Money is more important to people on this game than assisting your fellow gamer, who is new to the higher levels of the game.
I'd lot the weapons for gc seals too.

If you're at the point where you're doing HM primals, you should be able to get a relic weapon, especially nowadays where HMs are absolutely steamrolled.

If you're farming a HM primal for a weapon to seriously use and not just to get something for glamours or whatever, you're wasting your time.
