Whm, sge, smn and sch. I probably would include ast but I don’t play it enough to have an opinion.

If fell cleave cost 40 rather than 50 gauge, it would be more difficult to end on an ungainly number, but gauge generation would need rebalanced to compensate. Or the addition of something dps-neutral that allows the gauge to be fully emptied (either costing 5/10 or as much gauge as you currently have).

If anything the last balance patch just underscored how lacking the job has become. I wish I had the optimism to believe that it will be changed for the better anytime soon.
