as far as the bleeds in ML go, you seem to be doing fine, but having more crit will allow you to parry Taskmaster Askari a lot more. See stats paragraph later on.
Going gearing and into stats:
Craft a shield and craft a weapon. Shield ilvl is important and will provide more block than a hero track shield. Upgrade a gilded crafted shield into Myth whenever you get vault drops. Same thing with a weapon. Craft one, it will help with dps (which means threat) much more than any other slots. These should have been your first two gilded crafts. Please make sure you always max out shield with upgrades first and foremost, its our most important piece.
Once again: Shield > Weapon and Myth > Gilded Crafted > Hero. These are extremely important. Their ilvl is basically the most important part about them, so if they are non-crafted make sure you max them out before anything else
Your stats are fine like i said in the reddit thread, but do try to emphasize crit more than haste when getting myth track pieces/accessories, i.e. high crit + low haste rings like Cauldron's ring or any equivalent. More crit will yield more dps, more threat, and more parry. Simming droptimizer is extremely useful for this as any stat simming higher for dps consequently gives us more undiminished defensiveness. Do keep in mind that with sims, it tries to get you down to 18k haste, so you want to ignore any offset of haste and make sure you at least maintain 20k haste rating so that your SB uptime does not suffer. The bot does not account for human error so 18k is only good with perfect play.
