You get a hell of a lot more damage then just 400 from using a good bramble. A lot more...
COH? 2 skills, some DR, and resists? thats it? Ok, skills for a ww assassin don't help you out that much. You'd be surprised how little actually. Secondly, you get DR from fade, so why would you need it on your armor? Third, you also get massive resists from fade, so again, you won't need them on your armor.
At around lvl 75, you have all the skill points you need to make a complete WW assassin. After that, your just putting points where you think they will benifit you the most. Dragon flight, cloak of shadows, or shadow master. These are certainly not necessary, but they help a little.
Basically, your using COH to save points in fade. But what I am telling you is that you will have all the skill points you need left over to put them into fade. There is no need to save points.
COH is a very poor choice. There is no way in hell you would be able to beat a bramble ww'er if you use coh. No chance...
Also, cloak of shadows is far from worthless. Yocard, if you don't have any assassin experience, then simply don't make comments. But any decent assassin knows the value of cloak. Not only does it raise your defense, and lower your enemies defense, but it also blinds summons and minions of your enemies and makes them not attack you. Cloak rules. I agree a high level cloak may not be for everyone, but to say the skill is worthless just stupid
