I barely come to this section cause i rather to let Assassins build their own build more than imposing my preference. Since with this patch we're really lacking of point (same for Rogues) to make the "perfect build" for us, i'll try to guide you on what you like most.
Cooldown at lvl 1:
28-30 seconds 30 seconds
Cooldown at lvl 10:
14-16 seconds 23 seconds
Cooldown at lvl 10 with Guardian : 14 seconds
Grimtooth at lvl 10:
Pros: You can slow down up to 10 targets dealing 683% damage to all of them, which is kinda good for KSing at some point and running away when being low hp.
Contra: It waste a ton of points, for us points are useful for many other skills like maxing MoG or getting PW to DoT Rogues or CI.
2º Duels and 1v1
Pros: It helps as another "finisher" if the other skills are on cooldown, we kill pretty quick 1--5 seconds, and all our skills are on cooldown at that time.
Contra: You're wasting points on other useful skills like MoG or DW or CI if you max it, depending your preference.
Pros: If you group up with 5 Assassin's you can 1 shot up to 10 targets in a crowd and/or slow all of them for -50% mov. speed. You can also help your team slowing WoE Guardians while the rest is DPSing the Empellium (Shadow Armor at lvl 8 needed).
Contra: It lags alot when you hit 10 targets, so you need a high rendering computer to be able to proceed on the next skills or whatever it's your next step.
Pros: Pretty much the damage and the nº of targets you can slow down, i saw you don't have Shadow Fang, so unless you have a Mermaid lvl 4 or a good DoT pet to grind, i would highly recommend to max Grim to at least slow down mobs like on DW-Lower to back up your team or even DW- Upper if you like to solo.
Contra: Nº of Points required.
Edit: Cooldowns and damage.
