Guild Wars 2

So im new to this game and ive never played a Mesmer but i love the fact that they can use GS pistol Sword all that cool stuff. However how are they damage, how big are the numbers? And what role do they Fill in PvE since im mostly playing pve content.

Mesmer’s capability depend really heavily on specs. It damages can go from “almost inexistant” to “WTF happened and why is there a mushroom cloud?”. A good shatter mesmer is one of the best spiker in the game, and sustained damage of phantasm is to be accounted for in boss encounters. In PvE, you should have enough survivability to go full berserk without much trouble since there is good defense on all weapon set.
In PvE, you will be looked to mainly for boon stripping, projectile reflection, time warp and portal. Since you can do the first two with a lot of different specs, and the last one is a no brainer, it leaves a lot of builds open.
So, the main question is: which role do you want to fill?
The various build thread should then guide you toward this role (interrupter, boon dispenser, damage dealer…).

Mesmers with three phantasms up are great DPS. If you want big numbers, just put feedback up on any fight that needs reflects, you’ll deal like 50k damage on searing effigy and a couple hundred thousand on Lupicus.

In PvE, you’re generally just taken for reflects, pulls, boon removal and signet of inspiration if the group sucks at stacking might. You’ll be able to pull all of this off while fully gearing and traiting for damage, so there’s no need to use useless traits or bad gear to support since almost all of the support is built in to your weapon and utility skills.

Honestly, I was sold on mesmer when I saw how we levitate and spin glowy greatswords to attack. The mesmer class really steps out of the bounds of your normal rpg class. I suppose it might be related to a conjurer class and perhaps even harkens all the way back to the FF Red Mage class.

where as this game has no ranked/competitive team oriented fight modes, except tpvp.. however if it would have maybe guild vs guild (gvg).. mesmers role would be slot bot for your veil and portal timewrap other than other classes.. other traits re already on forums.. for pvp wvw pve
