In CBT, most magic monsters didn’t actually do “Magic” attacks. They were Missiles, and could be dodged. <_< So unless they changed it…it’s still useful, especially without a shield.
Yea, im going full STR.
Letting Finestra and gear make up for the crit rate.
Whats the point doing crits with low crit attacks? 
Even if ur crit atk is 0, u still doing 1.5x damage than usual. For pve, full str is ok, but pvp u still need dex for accuracy. Most people getting dex on swordy just for accuracy. U will miss alot on full dex player
When 1skill can kill 1mob, with miss u need 2skill to kill that. Thats why much better up ur dex atleast 1 in 5/7lvl. Well, it depend on each person preference.
The build you listed at the beginnig is not bad either, it’s just solely PvP focused. Yet Cata is not too weak in PvE as well.
And it seems restrain works on skills. So you can use rush to stunlock several enemies.
As for stats I’d suggest at least 100-150 DEX in any build, and then focus totally on STR. DEX is better early on and will indirectly boost your STR effectiveness. Just take into account that at rank 10(around lvl 500) 100 STR will bring you 400 patk, and 100 DEX up to 8% crit chance with STR build. With DEX build 100 STR will bring around 250 attack, and 100 DEX up to 16% crit chance.
DEX benefits you the most early game, while falling to mid game. Yet in late game it regains part of it’s power due to High skill damages. So the most effective way is combination of STR and DEX.
Also defense partially counters DEX builds (you can see a video with full DEX corsair lvl 180 dealing 1 damage on boss of the same level WITH crit). So you’ll really want some defense decreasing/ignoring if you go heavy DEX.
Thanks for the infos guys. Now i’m really torn between the non-cata or cata3 builds. I guess i just have to try both (given i have the time) 
We have to keep in mind that Stabbing takes a much longer time to use, so that’s a lot of time where you could be using another skill etc
Just a heads up
