Guild Wars 2

Alright so I am most definitely not new to the game in any sense. I have a Necro main at 80 that I’ve done basically everything with outside of PvP, and three other 80s, and this ignores the 12 characters I had in GW1 all outfitted with obsidian and the like.

Buuuuut… I’m pretty casual. I literally just play how I feel and do whatever I want even if it’s not truly what the class is supposed to do, so I tend to get my butt handed to me in anything particularly hard in PvE and anything period in PvP. However, I want to start trying to play more seriously, playing to the professions’ (and my own) strengths and meta, so I can more reasonably enjoy WvW. So my question is what do you helpful people think I should play as?

In other PvP type games I usually play a mobile no gimmicks spiker type, like the Scout in TF2, or burst damage based classes in other games. I also really really suck at doing any kind of organized teamwork, instead preferring to just run in and out of any situation I think I can assist with. (I definitely won’t play in groups often if at all.) I also tend to put about 10% thought into what I’m doing at any given moment so anything that requires really complex combos to be effective will be lost on me.

Obviously, this sounds like a description of the thief, but it might also be warrior or mesmer or maybe even engineer, so I just want some second opinions. Thanks in advance!
