To give Axe credits, Ruinator is one godly WS. Decided to get it to 5/5 and mess about on WAR/NIN with it, and I was impressed.

5 hits (DW) 1.0 fTP 100% STR and 37.5% attack bonus.

200 STR (248 inside Voidwatch) for 210 WSC
76DMG Weapon
16 fSTR
302 BD * 1.2 (belt / gorget) = 362 per hit.
Assuming capped ratio (37% attack bonus nearly guarantees this) of 2.0 (averaged), we got 724 per hit
27% DA (easy to get for WAR) in full STR WS gear, 5.54 average hits per WS.

~4010 or so damage prior to taking accuracy into account (75.26% of the time).

Resolution is still stronger, but only if you auto-cap attack.

Still only a WAR could pull those kind of numbers off, BST has far too little offensive JA / JT to push it. That and most BST I've seen suck at anything remotely related to damage, even with them being on tons of heavy DD orientated pieces.

For Exten, it's ~ok~. Best unstacked WS for DNC and THF, still it's lack of fTP copy and attack bonus leaves much to be desired.
