Expertise adrenals no longer increase the damage you do in PvP. They are only a damage reduction in their current state.
ever seen that "red glowy thingy" useally located in the back giving you 15% inc dmg in warzones?
Its not an adrenal, but im pretty sure thats what he ment
oh, and naked ppl dont have over 10k hp for this to be recorded to the scorecard.
its either fake (mulitple hits recorded) or hes fully geared out with over 1020 bonus dmg, and used bl, wz buff, 5x juyo form, vindicator buff, sunders/ inc dmg debuffs.
Still i dont belive annihilate hits for 10k. fishy !
