One of the most frequently-asked questions in GW2, at least in my opinion, is “what build should I use?” I think that if more people understood how GW2 works, they wouldn’t need to ask that.
In other MMO games, at least in my experience, there are one or two “superbuilds” for a few (or possibly all) classes, but outside of certain skills, traits, feats, abilities, etc., a lot of the “options” presented to you are absolutely worthless. People therefore fear coming up with a build in GW2 because 1) they suspect that if they don’t know what the current meta/“superbuild[s]” for their class is, or whether their class is even viable, that they’ll waste time and in-game money experimenting on a lost cause, or 2) if they don’t use the current flavor-of-the-month builds or overpowered “superbuilds,” they’ll be at a disadvantage compared to other players. For example, I played Diablo 2 for a while back in the day, and basically, if you weren’t a hammer paladin, a spin-to-win whirlwind barbarian, or some kind of sorceress, you weren’t going to get far; necromancers and amazons were often deemed outright useless. I’ve heard that in WOW, there is pretty much exactly one viable build per class, and some classes are decidedly underpowered.
GW2 is different. While some people will berate you for not optimizing your build for group play, every class is viable, and every class has enough options that pretty much any playstyle is viable.
People often ask me what the “best” build is, either for their class or in general. While some may disagree, the best build is the one you enjoy and that you understand how to use. GW2 is not a game where you can slap on the skills and gear a community-made build calls for and expect to win the game automatically. Yes, some people criticize the game for being too easy and facilitating zergs and mindless autoattacking, but if you’re exploring on your own or in small groups, you’ll lose if you’re not paying attention to the enemy and using a build you understand.
The first step is to find a class that conforms to your preferred playstyle. Other than dedicated healers and tanks, I can almost guarantee there’s a class for you. Ask yourself whether your current class is one that fits the way you like to play. If it is, great! If not, don’t waste your time—switch characters, try another class, and see if it works. Do you like micromanagement? Try a mesmer. Do you enjoy a simpler strategy based on surviving up close and doing heavy melee damage? Try a warrior.
The second step is focusing on what you actually want to do with your class. Each trait line caters to a specific style. Figure out what appeals to you and specialize accordingly. Do you like the guardian’s Virtue of Justice, which applies burning? Choose traits related to burning, the use of that virtue, and anything that works with traits that cause burning or improve the virtue—SYNERGIZE. For example, Radiance is the trait line that emphasizes burning and the Virtue of Justice. The 5-point trait causes blindness around you when you activate Justice. Major trait VI causes vulnerability when blindness is applied. Therefore, using those together gives you TWO extra effects when you use that one ability. Add in the 5-point trait from the Virtues line, and you ALSO grant might to yourself and everyone around you when you use Justice! That’s synergy, and that’s what you want to go for. Ground your build in a concept or two, and work towards achieving a certain goal when you choose your traits and skills. The more synergy, the better.
