Defensive Ideas for Machinist
MCH is def lacking in terms of defensive capabilities. Using a cross-class slot for Keen Flurry would be a waste.
Machinist has enough abilities to press tho, so I don't want them to just add another. I believe it's been stated by the Devs that the placement of the turret is important, so why not expand on that?
An idea I had would be that you can use your turret as a shield to reduce the dmg you take. Which would only occur if you are within very close proximity to your turret. They could even visually represent this with a line between you and your turret.
If your turret dies I would imagine that means you probably would have died as well. It would result in a dps loss for the few seconds your turret is gone. But it's a tradeoff between you dying or you taking some dmg and having to resummon your turret.
Another idea that just popped in my head while typing this is to add a small heal when you summon your turret. Might be a little OP tho.
