covert sucks, people gotta drop it already
Covert can be easily counter but no way does it suck.
But hey, if you can convince players to drop it, I'm all for it because it makes the game that much easier.
the shiv is/was alright. But then you realise that it is only worth it if you use it often and don't craft shivs yourself before getting a new one. As well as executioner being a much better alternative for it.
covert 3 marking thing is pointless already, hope I don't have to explain that to you.
and covert 2 is good, I won't argue. But like many other skills is so situational in that for it to work, you have to be crouching and the enemy has to be using listen mode for it to come into effect, if not then well it's pointless.
With agility coming out, we now have a true stealth survival skill.
