Guild Wars 2

All classes are viable in all content areas. Some have specific skills better than others, but it overall balances out.

Disclaimer: I don’t extensively play any of these classes, so I may be completely wrong. I do group with them a lot, however, so I’m not clueless.

Ranger:
I see rangers primarily as a DPS class. I’ll trust someone if they tell me you can have ranger tanks and ranger support, but generally all I see is DPS. They tend to have less party buffs and higher personal performance than other characters, and while they’re no slouches in melee, they’ve got especially strong range.

Warrior:
Good defense and damage both, almost regardless of spec. I typically see warriors that bring solid personal DPS while using shouts/banners to amp up the rest of the party’s DPS as well. One thing to consider is that the warrior is extremely offense-focused. They have OK DPS regardless of build, can spec for ungodly DPS, and even their support focuses on improving ally DPS rather than preserving ally life. Not playing a warrior myself, I don’t know whether this is true or not, but warriors are stereotyped as the “easy class”.

Guardian:
Guardians often serve as the defensive backbone of the party. They can be build to have good DPS, but what I see most often is guardians that have higher-than-average defense and group support. Almost any guardian build is going to have some semblance of support, and their innate abilities make them harder to kill than most.

Warrior is the most straightforward class, so if you want something simple that’s still effective, that’s the way to go.

Agreed. Always roll warrior first – it allows you to make the most mistakes and still recover relatively easily. Plus, you’ll get better as you play, meaning you’ll be able to better play other classes after learning the game play on warrior.
