Yeah, it seems like you were right about regular bf2 being safer. I need to check bf1 on whiff now
ex BF2 is definitely good for HT and Shotgun. For HT, it's a way past projectiles without switching sides, so you can push them into the corner instead of exbf1 which just keeps them midscreen. If you are too late or they faint the projectile, you aren't a sitting duck anymore and still push them back.
All variations benefit in the wakeup department. Also, armoring through pressure without getting baited into a punish or low-profiled.
Full Auto probably benefits the most from the timer change. She can get a life lead and try to lame you out a bit. The timer might hurt High Tech though, it's hard to say.
