Wanna throw Dark Knight a bone???
Are you trolling? The DRK 2hr is probably the best of the new 2hrs and is potentially one of the stongest 2hrs in the game in terms of how it increases your damage and how it inhibits the enemy. Testing shows it drains 30-50 TP per hit which means now only are you gonna be WSing a lot more, but the mob's TP moves will be completely inhibited. Throw on Tactician's Roll/Adoloquiem/Embrava and this new 2hr and you're gonna basically be spamming weapon skills. Now imagine 5 DRKs in an alliance using this move during perfect defense embrava. Normally during perfect defense the mob only had TP moves to really hurt an alliance, now the alliance will be impervious for those 30 seconds while the DRK's plunders all the TP the mob has been getting from being hit by zerging DDs. Now compare that to the DRG 2hr which just enhances the wyvern and heals it to full(Spirit Link heals 90% of its HP) and it gives stronger breaths(breaths that were resisted like nuts for 10-90 damage will do 200ish for 60 seconds..whooo and healing breaths heal a bit more which is moot outside of solo or failwhms.)
