Hunts are fine, the real problem is another: the only way (except daily mobs) to upgrade the current equip is to zerg hunts, and ranks A are NOT designed for 8+ players.
They should stop putting upgrades item into hunts, imho.

Done some A ranks, when randomly encountered, in the last month of 2.5 with 3 friends of mine and that was fun because there was ZERO zerg and some fight's mechanics were enjoyables.
