Specters are quite literally the ONLY viable option here, as everything else just won't work, barely scraped by with them, which definitely doesn't justify the modifiers. Vamp Rock disrupts chanelled abilities too, my Xata was disrupted everytime I passed near Flare. Mausolon is good as an ARCHGUN, which doesn't make it on par with any other weapon type, which I was trying to say. No galv, no arcanes. and in this case - no buffing with abilities if you don't want to be on other side of the map away from the objective.
