Im hoping SE releases an ilvl OAT Polearm Chauve-Souris/Corsesca again. I remember when it first came out, it was pretty much the best non ryu polearm and boy was it fun having a full time 45% OAT rate.
I had a lot of fun with my OAT polearm pre-RYU. But god was it a ugly looking thing. If they add a new OAT, please use a better model....
The Skirmish+2 polearm might be up there too, it has comparable base dmg to Upukirex with the base dmg augment(+25-27) and can get DA, and +WSD 5-10% and stuff too. Might push Rhongo out since using Camlann's for any reason is a terrible choice.
Ran some quick stuff on the skirmish +2 polearm.
Upukirex:810 DPS
Qatsunoci +2 with DMG+26, STR+8, and DA+2: 808 DPS
How the next part goes, depnds on what model the WS dmg follows. If it works like WS dmg+gear(phorcys, etc. proc on first hit only) then
Qatsunoci +2 with DMG+26, STR+8, WSDMG+10%: 805 DPS
If it works like the relic/mythic bonuses, and applies to all hits, then;
Qatsunoci +2 with DMG+26, STR+8, WSDMG+10%: 845 DPS
I haven't seen any testing on the wsdmg augment yet, so I dunno which it'd be.
