So from the Delve stuff, things that immediately spring to mind:
Qaaxo Mitaines B15 are now our best ACC hands
Qaaxo Harness A15 is a good alternative to Thaumas when you need good hybrid between damage and staying alive (even out damages Thaumas on some higher level fodder, maybe because of the STR/DEX, plus the highest evasion available from body)
B15 is great too, for stuff you're not going to dodge or with lots of physical AoEs. I will probably go the B path for stuff like AAs where there is always a chance you're going to get caught by an AoE no matter how good you are.
Qaaxo Tights C15 become our best defensive legs (+112 HP is ridonc)
Qaaxo Feet C15 definitely our best Mercy Feet now, B15 would be our best ACC feet (~4.25 more ACC than Pill. Poulaines +1, but with some STP added on at the cost of an equal amount of STR).
All in all the B path looks the most promising to me, since almost none of this (except the feet of course) are going to replace Pillager's +1 for stacked WS (crit damage is just too good to pass up)
Now if only it wasn't 12 mil+ to cap pieces right now.
