its pretty bad. the bleedout mechanic is terrible, not a fan of the current TTK, the UI (not ingame UI) is really bad and a pain in the ass to navigate. to unlock a new weapon that you have earned through rankup, you need to quit the game and load up the armory UI, not your character UI. Weapon customization is pure fucking garbage (you have 4 upgrade paths that you unlock with BFV points. if you want to try one of the other paths, you need to buy another copy of the gun using BFV points, then spend more to unlock the other path's upgrades. repeat as necessary). the various graphics settings and clutter make the game harder to see (and the action being more run and gun is exacerbating the issue). the actual quality of building and terrain textures has been a downgrade from BF1 as well.
vehicles seem pretty pointless at the moment too. tanks get raped by assault and support and the planes dont seem to be very deadly against ground troops, making them way less fun than BF1. They seem to exist solely for dogfights that aren't up to par IMO.
anyway, thats my review based on experiences playing BC2, BF4 and BF1
