Never tried that one before. I usually go either with my Ranged Glass Canon and we pretty much kite the mobs and keep their number low. Or even better, its when everybody is a ranged glass canon with me and my Hybrid Guardian. I keep the mobs on me, my omnomberry ghost keep my hp at 100% pretty much all the time, and i got enough toughness to stay alive when they knockback me 3-4 times (got two break stun that help too). The 4 other simple smash the mobs that a keep all together. This way we keep the mobs' number to a minimum, we even go out of combat sometimes between the waves.
This is good build for bad players and bad party composition
Some of my best friend are casual player, that you call bad players and i really don't like it. You have no reason to be mean against someone that just enjoy a game not playing it like you play it. I agree with a part of what you want to say, but i totally disagree on the way you communicate it and your disrespect while doingg so. In the end its a game and people can play the game as they want, you can propose them some way to improve their build, but what your doing is not a good way. Sonic Boon is a good build for casual player which represent a LARGE majority of the players. And surprise, this large majority that you seem to dislike are the ones that allow you to play GW2. The hardcore gamers are not enough to keep the game going, and that you like it or not helping these casual player by explaining dungeon when they come on your party is a better way to improve your and their game time and not by kicking and insulting them.
Maybe ludicrious are a strong word. But i agree on that. The term ''invincible'' should never be use by someone posting a build. And the words ''Great Damage'' is often wrongly use. Only Glass Canon build have great damage, because they sacrifice all they can in defensive to reach the best damage. How a more defensive build can have more defensive and more offensive at the same time?? Its just a bad choice of word.
