Just finished exping on Greater Colibri in a SAM/WAR x3, NIN/WAR, WHM, RDM pt.
Gekko's continued to impress, the consitency of it is just insane. I had exactly one WS under 1k in about 2 hours of exp, and nearly all of them were 1300ish for normal 1 hit, and I capped out at 2169 Gekko at 200% TP (DA proc) with same setup as above, no songs, corsair buffs or food, but the RDM was using Dia. ACC was not an issue, although I felt I could of used a little more, so I did put woodsman ring back on for melee.
I think one of the major things that needs to be tested is Hauby+1 vs Osode for SAM/WAR WS. I'm still leaning towards Hauby+1, but Osode could very well end up being king.
I was afraid the -6 DEX (thus -6 acc) on alkys might of been an issue, but after a few pts now, its obvious that the acc loss means next to nothing in an exp setting. Maybe on more evasive HNMs it could be an issue.
