LS mate working on WAR and asked questions about the best merit WS. He's working towards an Ukon and has no plans for a Relic GAXE.

Looking over there three, for the interim.

Resolution
4.59375 fTP (all 5 hits no DA) 100% STR
Jingang GSWD for 5-hit

Upheaval
4.0 fTP (would it be better to use VIT belt / gorget due to no copy fTP?) 4-hit 100% VIT
Magian WS+10% GAXE? / OaT GAXE? (no idea what the best non-RME would be here)

Ruinator (/NIN ~shudder~)
6.0 fTP with five hits, 100% STR, 37% attack bonus
Magian Fire Axes? (Not sure if there are better options for this)

I'm only including the Axe one due to it's retarded fTP, STR mod and Shoha like attack bonus (on all hits).

Again this is an temp solution until he makes an Ukon. Upheaval looks really weak compared to the other two, is there some special setup that makes it stronger?
