Very good point.
I have never gotten to the collector base as a vanguard (found the class too boring) but I see what you mean.
I am assuming that the Soldier and Infiltrator have the quickest times thus far?
It's pretty balanced actually - in terms of "real" speed time dilation can sort of work against you. Both Soldier and Infiltrator dilate time quite frequently, even though their game-relation kill speed remains high.
I think the reality of it is that Warp explosions are extremely hard to beat when doing a lot of forward movement through weaker enemies, so sometimes what you gain in firepower you lose in teammate ability to create the devastating Warp combos.
All of those Collector-based missions favor Warp combos generally because of the Barrier prominence combined with the frequent ability to ledge-kill. I think maybe if you take all of the missions and average it out, Vanguard might win that contest because they are the most consistent outside of a few snags.
If you look at them separately it's much more varied; the mission you posted for example, outside of the Colossus itself, probably leans Infiltrator/Engineer because it greatly favors AI Hacking and Squad Disruptor when combined with full auto weapons. Squad Disruptor alone with full autos make, say, the Soldier a strong choice, but hacked enemies just
wreck each other on Insanity so it's hard to match without that particular skill.
Vanguards are definitely fast though, there's no arguing that. I think the only reason they don't blow the other classes out of the water is simply the global cooldown; they simply can't synergize with squad mates for Warp combos well because their cooldown is constantly tied up in BC.
