Well, the idea behind this update was the best one yet, but the way it came out is a totally different story. So many achievements are bugged(Equalizer achievements, milestones etc), some have wrong triggers (Death from below achievement where it states that you have to kill 10 airborne enemies and what you really have to do is just kill them with body shots), and one day after the update was out, Steam was down and ppl didn't get any weapons and now they have to idle for them! To sum things up, the weapons are nice but some of them change the way entire class is played, the achievements are well designed but buggy and as for the crafting, it's a double-edged sword: it's a great thing that we can craft hats now but, idle servers will prosper from everyone just waiting to get more items to smelt. All in all, a nice update that has been partially ruined by the bugs. I hope that Valve patches it soon.
