I played most of the last year on PS3 and just recently switched to PS4. I never had a problem getting out of stuff and so not much has changed. The biggest thing I notice between PS4 and PS3 is that Brangwine actually loads right off for me (as does every other NPC that typically has a ton of players standing around it). I also zone quicker and enter and exit duties faster. I can finally see hunt mobs and play 72 person Frontlines Slaughter. Aside from faster loading, I haven't noticed much change. PS4 is certainly better than PS3 but your problem getting out of stuff might be caused by something else (I'm no expert on this).
Edit: Oops didn't realize you said PC instead of PS4. That might make more of a difference, I don't know.
