I've had an hour or so on it, obviously with 1 map I was getting destroyed. First spawn in I did glitch through the map but that's been the only real problem and it didn't happen again.
You seem to die really fast but ttk seems slow when your dishing out the hurt not sure why that is.
I had a go as operator the self revive didn't seem to be an issue as generally you overkill people I was running it but never got the chance and I died alot.
I also tried mechanic and liked the fact that the SMG didn't seem as weak as what they seem in bf4 which was nice, the laser sight looked a bit weird and rough tho.
As I improved I got a few service stars but didn't get chance to try the new unlock system yet.
Of the 2 game modes blood money is the best from my perspective heist is just basically capture the flag and was over really quick whereas blood money if the sides are balanced will last a while, I found stealing from other teams vault was easier than the main cash pile.
So far I'm enjoying it, it is manic and very fast paced I'm interested to see what other game modes will be in the final game also.
Edit I don't like the running animation it does feel like your running with a limp.
