uhm, well, I could recomend you this build
You still have 8 free points there.
Im quite the weirdo so I dont see much value in skills like <Mark of Genocide> or <Shadow Cloack> but well, thats totally up to your choice.
<Dark Illusion> is a skill I love a lot, a ton, I would say its my favorite skill in the game, but is not a requirement for an Assassin, you can pretty much drop it (I still would put one point in it tho XD)
<Poison Weapon> is weakened in a very drastic manner, however using it is NEVER a negative DPS, since you never actually use it mid battle and it can proc passively from any of your attack skills, however the current DMG scaling per level is really poor.
You won't really need <Combo Training>, <Grimtooth> and <Shadow Strike> will do the trick for insta Combo Point maxing most of the time. But if you still feel like getting it, lvl 2 is more than enough.
<Deadly Blow> DMG scaling per level is very poor, and is quite dubious if it actually beats <Double Attack> in the end.
A 5 Combo Points Lvl 1 DB = A 4 Combo Points Lvl 5 DB
A 5 Combo Points Lvl 5 DB > 2 DA (Damage wise)
A 5 Combo Points Lvl 1 DB >= 2 DA (As in, the 4 hits of DA Land, Crit or Miss)
If you like betting, this is a good skill for you.
Grimtooth is perfect heal every 10 seconds and will only get better as you go up. If you want to solo stuff, this is a must.
<Shadow Fang> might not shine so much in a 1v1 as most of the lvling part is, but to kill many at once is awesome, specially while you wait for Grimtooth. And if you can master Kiting, this is your best companion.
<Shadow Armor> is a must, you do well on including it, when you get it, you max it, or you max it, no questions asked.
We don't even need to start discussing about <Shadow Form> XD
<Shadow Assault> has 2 utilities, one is to instantly jump on a target 20m away, and another is to knock that target down for 3 seconds. The damage output outdoes DA since level 1, but the animation is pretty long and you always want this skill for either of those 2 utilities and never for the damage it deals, so level 1 is all you need and want (unless you are a fully PvP focused player).
<Shadow Strike> and <Shadow Explosion> are a set, get one, and get the other, no need to get them lower. The cooldown might seem long at the beginning, but later on you'll get them back real fast (to the point that DB will seem even more pointless).
Good luck!
