Which do you think would work better for PVP?

Hello. I'm semi new and am kind of torn between choosing Mesmer or Necro for my secondary profession. I'd like a strong health degeneration and cast interruption, as I think that that would be important for PvP battles, although I could be wrong. Pretty much, when I get better at the game I don't want to really regret my decision. What do you think works best as a secondary profession for the Elementalist?

Thanks a lot.

Mesmer. Has both good degen and cast interruption.

Alright, sweet. Thanks a bunch. I'm trusting you

as an addition you can always change secondaries in the desert if it is a pve char as many times as you want and you can always go back to a previous profession and it will remeber the skills you unlocked. If it is pvp then you can just keep rerolloing till you like the combo.

for elementalist, mesmer is the best idea not because of degen and interruption, since you will be focusing on elementalist stuff, and energy storage. what the mesmer secondary is good for, for an ele, is mantra of concentration / resolve...

Your character won't be powerful enough to PvP until you get to the point where you can swap secondary professions freely.

But your original choice of secondary profession will be the one you've gathered many more skills for, so the choice does matter somewhat.
