The heists are changed just enough to keep everything fresh, playing in third person is super fun, enemies are really fun and tough, and it's basically just a faster paced PAYDAY 3, like Smash and Grab.
Also the road rage map is so different, and more like green bridge, and if they do something similar for the rework in the future, that would be AWESOME.
I've played a couple Solo Overkill matches with it on NRFTW and TTS, and both were extremely easy, and I was using a fairly standard/basic Soldier tree build.
Dozers hardly spawn until later into matches, since I get so many SWAT kills so fast, by the time they're hobbling over, they're already walking back.
And since SWAT AI stays together in groups, spamming throwables and murdering as fast as you can is so so easy. Especially with objectives where you are defending an area, or if there's an area in the map with a choke point for cops.
