Dear lovely Gm or Admin,
Since GS Tracking is still OP and not solved yet, maybe I would suggest you increase other job's damage as well.
For instance, increase LK spear boomerang by 1000%, increase HW soul strike by 1000%.
Perhaps 1000% sounds scary, just make sure all jobs have a skill, a ring, and a weapon that can deal 100-200k per attack.
No point that one job dominates all others, right?
