I find that I enjoy spamming different things on different classes that I play, so I can't really say I hate any one thing much more than the other.

When I am playing my healbot, I will totally steal your kills with Jesus beam. Because Jesus beam. :-D Otherwise I'm going to have to hug them all to death and that just doesn't work too well.

When I am playing my stamsorc I hate those who spam Jesus beam and have even taken the crappy morph - Venom arrow rather than poison injection just to interrupt your Jesus beams. And your rezzes.

When I'm playing my ranged magblade, I hate DKs and their wings.

When I'm playing my stamwarden I absolutely love pelting DKs and their wings with birds. I'll give you some shalks as well for good measure. Too many days played as a nightblade destro/destro or even with a bow in "the old days" has given me a sincere distaste for reflects.

Whenever I get around to PvPing with my DK, I will probably hate the wardens and the bird swarms.

Basically, when the shoe is on the other foot, our perspectives change as well. I am happy that I have played most classes both solo/small man and large group.

I haven't played stamblade in a long time - primarily because I refuse to re-create my original main character and she's always been a stamblade. Even when stamblades were horrible. Sadly, right now she's stuck on a faction that I do not often PvP on, and also has nearly all of her skill points dedicated to things like crafting, thieves guild and dark brotherhood. One day, perhaps, I will proctard her out, maybe. Perhaps I should see what all the fuss is about from the other end.

Honestly since I only care about group PvP my chief concern are focusing down people that affect group play, it's never really about personal annoyance. That said, yes, these are all pretty frustrating things to fight against.

Bombblades should of made this list

yeah snipers then templars for me.

I really don't like healbots, but nightblades running mark are #1 for me

Dive needs to be dodgeable! The excuse that its dodgeable cause its slow is bs cause when a warden spams it one can only block it for so long and if it would be dodgeable it be the same as no one can roll all the time nor wont evation have a to big of an effect on it.
I see a warden do that I jump him, beat him in the ground and thus show em that skilled game play is way cooler!

I hit everything with force pulse. I must be annoying and proc my magicka/stamina cost increase poisons.
