I've never been good at PVP. I've loved individual PVP games for certain things (World of Tanks for simplicity and action, Planetside 2 for the epic scale and teamwork, Tribes for flying etc.) and consequently gotten ok at that kind of PVP.
But no matter how hard I try I really, really suck at this kind of PVP. Idk what you'd call it, executive reasoning, decision trees... having this rotation but in situation A having that rotation unless class X appears in which case apply curses 1 and 2 except if they have this particular miniscule nondescript box next to their name in which case use ability C all the while remembering to move and position and LOS and tab target the right things and guard and assist and not look at your keyboard or ability bar...
I could handle the knowledge, given enough time. But it's the speed of processing everything on top of the manual dexterity and APM that I don't think I'll ever reach. It stresses me out and is really not fun at all.
All of which is a longwinded way of saying that I'm a total scrub who doesn't really enjoy SCs, or being shouted at when we lose one, who finds healers very difficult to use, spend a lot of my time in-game farming or in PVP tend to stick to straightforward spammy classes like WEs, consequently shouldn't be relied upon BY ANY OF YOU FOR ANYTHING

(except maybe as bait) and in the original game I most enjoyed the large back and forth battles with less focus on individual skill and more on the objectives and the bigger picture - battles the scale of which we are yet to see here.
So, PVP. But with a fairly large 'but'.
