Rubberbanding GW2 Ps4

I have two Ps4's running side by side, (me and GF) and we do love this game. 

Some games such as team vanquish, turf takeover, Make us lag a little bit. It's kind of annoying we won't get to jump or use our powerups and normally die. 

My ISP is 75 download mbps, and 7.5 upload. They're close-ish to that mark. 

I used Google DNS, and It made the rubberbanding a little bit better.

Wondering if there's anything else I could do? sometimes it's really annoying. 

I checked your connectivity list, all that is checked and done. 

On a side note, do you think DNS might be better/faster than Google?
