Yep, now we have a bugged skill which can be used with a pistol… YEY 
But seriously, from launch and rank 6 this game’s totally failed to deliver the “assassin” concept. They have classes like Corsairs who’re able to do something while dual wielding (and not just use offhand stats to boost main weapon skills), Shinobis who can go invisible and do high risk attacks by cloning themselves and rogues who have bonus for attacking from behind, but it simply doesn’t work together (not even in the same base class tree) nor does it follow a common theme.
Current corsair updates have pretty much been consolidated as a support class for archers (it also boost its own pistol skill, but seriously, that’s gotta be the WORST Circle 3 Rank 7 skill in the game), without any improvement towards dual weilding and damage dealing. Every single problem people have talked about in this and many other feedback/bug report threads is still here. Have I mentioned worst circle 3 of rank 7 content?
Rogue’s in a even worse situation: it’s a one circle, which’s far from a wonder. Whenever you go rogue 1 for the sneak hit buff you’re stuck with having to equip Werewolf cards, reducing build diversirty by a lot. If you so dare to go further on Rogue you’re doomed to a really buggy Backstab skill which hardly procs the bonus from attacking from behind with it’s incredibly small hitbox and buggy damage mechanics. DO NOT, I repeat do not, venture burrowing yourself or you won’t even be able to use your own class skills. And no, Hackapell doesn’t save the class, buggy mechanics are still there alongside hacka’s own set of problems…
Back to swordies, Shinobi’s been dragged along the murmillo compability route, so it’s basically a shield-weilding (WTF!) class now. The compatibility skill list for clones mainly includes skills which can be boosted by wearing the Cassis helmet from Murmillo, with a few extra hardly relevant exceptions to any assassin themed build you could come up with a Shinobi, for instance clones not being able to copy any corsair skills. (Besides buggy mechanics of its own, obviously)
I guess that’s it for assassin themed classes as of now. Let’s hope IMC’s devs can actually do something about it at rank 9 since hope’s long gone at current rank 8 content.
TL:DR: Cheers, fellow assassin-denied saviors. Let’s all go back to playing our useful clerics now (who needs an assassin when you can bring about the Inquisition itself, right?)
