Guild Wars 2

I couldnt tell you the exact quest name for the life of me, but I was doing the story quest where you go to the sewers with your mentor and the monsters in the water were able to go through walls, effectively making me hitting them impossible. Forgal was able to follow them through the wall too for w/e reason.

I only noticed this on the Jellyfish monster in the sewers during that mission.

so im back after a long while away from the game (almost 6 months). when i left i had 3 level 80s (warrior, engie, theif) and now that ive been gone so long, im lookin to make a 4th 80, something i havent hit 80 with already (which includes every other class)

however, ive played every class, just not at the high levels. I already know im interested in making a light armor class, so that narrows it down to Necro, Ele and Mesmer.

I played necro to the high 70s then got bored before so thats off the table. so which between ele and mes should i consider?

I plan on WvWing and doing very little, if any pvp.

thanks for any input.
