OP is mad because they don't have their min-max'd classified Striker 6 piece from Div1 and have to actually use cover in a *gasp* cover shooter. They are also mad at health mechanics (armor plates versus magical injections) because it requires them to take the time to swap the plates out. There is a lot of salt in general about having to maintain situational awareness and utilize critical thinking skills to avoid an enemy AI that rushes, flanks, and does other things rather than just playing whack-a-mole from behind the same pieces of cover, so OP can just stand there and apply DPS until there's no more moles left to whack.You are my new forum friend whether you like it or not!
I can give you some of the smaller issues like vaulting/object collision and getting stuck on seemingly minor items in the road, but its a minor gripe you've peppered in there to try and conceal the raging butthurt you've festered because you can't apply all the (bad) habits from Div1 to Div2.
