WvW enthusiast considers return to GW2

I played GW2 from launch through Heart of Thorns; have lvl 80 warrior & ele but have been away for almost 6 years

Enjoy WvW more than any other aspect of games. Been playing Elder Scrolls Online but tired of WvW lag there.

Have precious little time for gaming, usually 10-12 hours per week

Have been away for almost 6 years

Totally lost at the moment in GW2, can't remember anything

Should I:

1. just stay with ESO and make the most of it
2. Find an efficient way to become effective in GW2 WvW with one of my characters

Thank you

I don't do alot of wvw at the moment, but I have a world completion map clear on Saturdays 8am pst and am doing Path of Fire map clears on Tuesday at 4pm pst I do -  that would be a great place to ask questions and get you back on track.
