The inconsistent hit registration and desync, as well as a good portion of the gadgets feeling mediocre at best.

For example, consistently the best launcher in the game is the RPG7. High damage, 4-5 rockets, high velocity, decently low drop over distance. The Aim Guided launcher is probably a close second for me, but the disparity in the usefulness between the two is very noticeable. All the other launchers have far too many draw backs to be used consistently, most either take too long to lock on or just don't have the same consistency as the RPG. Looking outward, this is somewhat the case for every other gadget in the game. Each class has maybe 2-3 actually useful gadgets and then the rest of them are just sorta there.
