Vermial Bhuj has already been left behind. Just comparing it with the WSD+10% trial, 8 STR is going to win by 2 base damage during TP, and even though it offers a significant boost during WS it gets demolished by that 1.1x multiplier on Sumeru +1. The 8 STR gets worked out a few times inside the damage formula, giving it a pretty static effect, while the weapon skill damage gets tacked on after everything is said and done.
If the choice is just between those two, Sumeru +1 for sure, but other trial options are further ahead, and by a fair margin.
I believe the thread was made when we were at lv 80, when we didnt have Sumeru +1.
For level 85, the comparation should be Sumeru +1 vs Atlas +1 vs Barbarus Bhuj
D104, 488 Delay, WS damage +10%
D108, 482 Delay, 8 STR, 22 Atk
D112, 488 Delay
