I'm kinda miffed I can't use GS effectively in raids/strikes/fractals as mirage, I like the ambush skill for GS, but the throughput is just ineffective. Almost all of the extra damage from the spec come from imaginary axes and the trait that gives additional ones on axe skill use. (To be fair, its autoattack also has ridiculously heavy condi damage as well, far and above anything the other mirage weapons could generate, either on plain auto attacks OR ambushes. )
I prefer choice, and I feel like making the elite weapon THE choice kills the spec sometimes and makes the elite specs feel more like pigeonholing than an actual extension of your class. I'd say good traits are ones like Chronophantasma that work well with ALL weapons and not just one.
I'm not saying make the elite weapons bad, I'm just saying it feels bad when there's only 1 weapon choice for an elite.
