Same, once I tried the WH, I loved it. They were alright on the Open Beta, but Mythic I guess bumped up their PVE survivability by tons. Now I can take on 3 things that's 2-4 higher levels than me. Granted I can take 2 down and the third to 20% health before I go splat, but still. I focus on Str/Ball/Wounds/Toughness and in that order. Going down the Confession path. I always use BBoPurity for the Init steal, helps me do more crits and evade more. I Snap Shot a lot when I get to peoples side. If a Black Orc is rushing a healer, I loop behind him, Snap when parallel, and the bullet usually snares him. This gives me time to do the Combos. Always focus on one target that's getting attacked. That will speed things up. If it's taking too long or they got too many heals coming, switch targets. I usually DoT/SnapShotSnare Tanks here and there and Razor the Support classes.
So, T1 RVR combo:
Fervor x3 /Razor x2 (any order)
>Burn, Heretic! (so now you have weak DoTs nibbling, 2 good raw damage, and a high-powered DoT that chews through Tank and Cloth armor alike)
>Razor/Ferver until 5 (or adequate) Accusations
>Absolution (Rinse and repeat if you have good support. If the guy is still at half health, DoT him again with Burn, Heretic! instead of the Abso, and when he's about to die, Absolution for the killing blow.)
T1-T2 RvR (only level 14 atm, I use the Emperor's Ward tactic and +EXP Renown Tactic)
Incognito
Burn, Armor (Throw this ONLY on Melee classes, works great on MDPS like Maruader and WE. As they begin a attack chain, they damage themselves.)
Fervor/Razor Strike until 5 Accu.
Burn, Heretic
F/R again, depending on the enemies health level
Absolution OR Trial By Pain (Now I know this is an alright skill, but this always gets me the killing blow, and it's great tool for when the run away. They usually have a weak HoT on, so this cuts through it)
Tips: ALWAYS use Get Thee Behind Me! This is such a useful skill when getting attacked by many folks. If you can, Detaunt with that and then Incognito away. But I usually die 60% of the when that happens, lol.
