Having read the recent interview, I'm aware now that all jobs are being looked at for balancing/rebalancing. With that in mind, and within reason, let's offer up suggestions of what we the players would like, in hopes that it will be taken under consideration going forward.

I would like to begin with Machinist:
- No casting stance. Perhaps an ability or two can retain a cast time, but make it worthwhile at least. This would naturally apply to BRD as well. Return them to being mobile, mid/long range physical support.
- Visually, get rid of the Gauss Barrel in favor of a "Gauss Mode" if you will. It's been universally hated by the MCH players, and can easily still be seen as a buff/stance marker if there are concerns of not being able to identify players using/not using it. In fairness, consider making the shot combo a standard, consistent one. Remove the potency of shot procs and apply it overall to the usage of the Gauss Mode, IF we simply must keep the stance as a whole.
- Merge Dismantle and Rend Mind. They share a cooldown, they're fundamentally the same skill, and Virus is an ability that effectively does the same thing in one skill as opposed to separate skills that take up 2 slots. Similarly, Leg Graze and Foot Graze offer different debuffing effects and thus don't really need to share a cooldown. SMN's Tri-Bind and Miasma offer the same debuffs but do not share a cooldown. There is little reason for 2 separate MCH skills to share a cooldown.
- We remain the only job in the game with no self-healing skill or access to a cross class ability of the same type. Similarly, we lack the ability to cross class a defensive skill beyond a parry increase, which currently doesn't help much at all. With Parry changes being considered, I (personally) am willing to wait and see if it proves to be a bit more effective, but because of the classes we have to pull cross class skills from, we are at a loss for damage mitigation and minor self-sustainability.
-Improve our running animation. The weapon arm is too static, and the way it's held in motion is impractical.
