I was going to check out GW2 just to see how WvW stuff is going, relive the old DAOC days. But the only real guild doing it on my server demands you run a specific meta build. They also want access to your GW2 API to confirm your build lol.
Sounds neat, but no.
Fortunately that isn't the one and only way to play wvw.
A lot of organized/gvg guilds will demand you run certain meta builds/classes, some take this very seriously, some also don't. Unfortunately running as meta as possible increase your chance for success in fights, especially if you're running in heavy numbers it can be almost unstoppable. It's very hard for groups to run under a certain amount and be able to smash other bigger organized groups. I see it every day when a 20-25 man group tries to take on a 40-50 man boon ball group and get absolutely demolished, one or two fights is enough to chase the smaller group off the map. Or even numbered fights like full squad 50v50, the one with the best tight group comp usually wins. Of course a lot of it comes down to the competence and positioning of the commanders involved as well, a lot of them are lazy and just want the boon spam to carry them so they stand in spots too long and eventually the aoes overtake them.
Having said that, those type of groups aren't on all the time, so there's still plenty of room to run small group/roaming/pugging as well. There's nothing stopping you from running along side those groups on your own either, other than if they're hiding the group with hidden commander tags while doing guild runs, but even then oj's are dead giveaways where groups are on the map. In fact Maguuma is a server known for it's clouding, which is practically every player on the map is a roamer/ganker with the ability to sync with those around them and pick apart groups, even the meta heavy groups, who mostly hate fighting Mag due to not being able to lock them down in clumps for aoeing. If nothing else you can also switch servers too, pretty cheap to move to most NA servers right now.
Personally I don't run in squads, as I tend to want to do my own thing with my own build at any given time, and as a mesmer I can easily switch from being a roamer, to a group boon stripper by switching out a couple skills or template that takes 2sec. It's also like playing the game on hard mode trying to survive fights sometimes from other gankers and groups without having the minstrel support up your ass healing and cleansing, pretty hairy in smc sometimes playing like this.
Balance is still an issue for me in this game, especially how much they've nerfed boon stripping the past couple years, which has only helped those meta heavy boon ball groups, further increasing the divide between those organized groups compared to small organized or pug groups, where you're practically forced to run the same perfect comp in order to beat them, as the 5 target cap doesn't help. And also their balancing doesn't seem to have any boundaries for handing out skills to other classes/specs, as seen by their guardian willbenders being made like thieves with all the movement they have on top of all the defense/support their class already had. Or them trying to make more "low intensity" builds where auto attack does a ton of damage which they hope would help bring up the skill ceiling on damage numbers for strikes/raids, their mechanist and engineer rifle rework being the latest examples of such. But overall I still love wvw, and I love messing with groups with pulls, so many times I've yoinked commanders off walls only to see their entire zerg follow them out, and defending the objective came down to one simple skill. Being a meta slave bot to a commander isn't the only way to play it.
