Spells
Deadly Haste - For 5...25...30 seconds, half-ranged spells cast 5...41...50% faster and recharge 5...41...50% faster. Your Deadly arts attribute is increased by 2.
Helps melee sins get more out of DA. Boost caster assassins as well.
Locust Fury - For 10...30...35 seconds, you have an additional 50% chance to double strike while using daggers. Your critical strikes with daggers do 25 slashing damage (armor affected).
Helps the skill out, Locust Fury begs for attack buffs to be added on to it and this change just helps assassins dealing damage. Also the CS damage boost affects skills too so it's not one-dimensional
Shroud of Silence Elite Touch spell. For 1...6...7 seconds target foes spells are disabled. Your spells are disabled for 15 seconds. 20s recharge.
A 5s spell disable at 9 DA, every 20 seconds would have more niches then it does now.
Shadow Form - Enchantment Spell. For 6...11...12 seconds, you have +15 Health regeneration move 33% faster and +100 armor. This enchantment ends if you successfully hit with an attack or use a skill.
My personal opinion is to make it an elite Feigned Neutrality. Good for running, survival and tanking, friendly to new players. Still some farming ability in there.
Attacks
Temple Strike -15s recharge
Golden Skull strike -10s recharge
20s recharge single target skill in PvE that doesn't do damage.... Yes Temple strike is awesome but for PvE? Yeah come on. Golden Skull strike...well I don't even know wtf it's purpose is, might as well just take a BHA ranger, that would due the same thing but unconditionally and for longer.
Shadow steps.
Aura of Displacement, Shadow Meld - 10s recharge
It's not the same situation as PvP, a 10s recharge is not a problem.
Shadow Prison, Dark Prison, Beguiling Haze -15s recharge
Again for PvE it's not a problem. they're 10-15 energy to begin with, and Beguiling Haze would be competing with BHA.
Shadow of haste -
For 30-60 seconds you move 15% faster than normal. When Shadow of Haste ends, you return to the location where you activated Shadow of Haste. 30s recharge
The above is actually a previous form of shadow form. So I'm suggesting a revert to this. This previous form of shadow of haste was arguably the strongest. Assassins and /A secondaries A permanently maintainable IMS that doubled as being a safety net if you caught yourself in trouble.
