Trying to decide profession... Pls halp.
Well, it’s really up to you and what you like.
However, the teleport does not work for jump puzzles. Blink will not allow the Mesmer to traverse over “impassable terrain” like empty air, so you cannot Blink from one platform to another in the vast majority of cases.
Portal is really useful in jump puzzles, though. You can use it before jumps that look especially hard and then place the exit if you fall and just port back up. You can also use it to help friends when they mess up, or finish the puzzle for people who want the rewards but don’t like jump puzzles.
I’ve really enjoyed using Portal to help friends in puzzles or just help random allies who show up while I’m doing one. Also, there are jump puzzles in the WvWvW zones that give you a guaranteed 2 siege weapon blueprints (includes siege golem), some badges of honor and three pieces of 79-80 gear. If you like jump puzzles and some light pvp, they are great places and reset daily with the daily achievement.
I can’t compare Guardian and Mesmer for you because I’ve only really played my Mesmer. However, the Mesmer is great for helping players (Feedback, Nullfield, Mass Invisibility, Veil, Time Warp) and is solid support in WvWvW fights. Unfortunately, though, in WvWvW you won’t be able to “tag” a lot of enemies due to a significant lack of AoE. So if you’re really worried about getting loot in big sieges, that’s a large negative.
Be forewarned, though, the Mesmer will tend to kill things a little slower than most other classes until you get a decent set of traits under your belt. Even then, it can be rough without a solid build and a really good understanding of what all of your abilities do.
Thanks guys! bumping this for more comments and halp.
