I'm not even gonna try to guess what you tried to say there.I understood that quite well but if you add the fact that i spend most of the time getting her to warden level 20 and grinding gold to buy the upgrades it allowed me at the time + stat accessories and the dmg i receive is the same then yeah i can pretty much say they are mostly useless .
If you in fact level your strength, by using strength attacks, you will receive less stamina damage per hit taken.
Are you aware you can use Cleave or Skewer to reduce that healing? And using Slam removes it completely, though the doctor might restore it with a shot, but that's at least one shot less aimed at you.because it self heals like crazy +the doctor shots that drain your stamina + and mobs resurrection while trying to dodge disarming effects and stuff.
The boss can be a bit RNG-dependent, depending on your build, but it's not that hard. What I like to do is use Ki+Focus and hope I counter the 2 adds, while using Slam/Cleave/Skewer on the big slime, possibly dealing +50% of its HP with one hit.
Having the Confident buff helps, but you don't want to taunt and make the rogue or the nerd angry. Use Flaunt if you got it.
