Is Phant/Mantra the only spec for group PvE?
The difference in damage output between the phantasm/mantra builds and everything else is absolutely massive. As much as I’d love to say that condition builds or shatter builds do comparable damage and can be run, it’s just not true. Additionally, phantasm/mantra builds have traiting that lines up with a lot of the heavy support that mesmer can provide, and that’s not the case with other builds.
tl;dr: Yeah, it’s the only game in town.
I think empowering mantras at least should be reworked. It’s a bit ridiculous that the main thing with a mantra build is having them prepared rather than be encouraged to use them. But that’s not the only thing that could use a looking at with mantras I think.
As for Shatter, I really think Mind Wrack needs some kind of DoT or damage synergy added to it. A goal being not to increase burst for pvp, but to make it more viable in longer fights. Either way, I am also not really a big fan of phantasm upkeep. For me it’s like taking the complexity out of the class entirely. I am a way bigger fan of manipulating illusions than being a minion master I suppose. There should be a way to play both types and feel satisfied in PvE.
