I've pretty much stuck to playing Vasari since picking up the game, and one of my favourite ships of theirs to play with is the Antorak Marauder. It's AoE speed buff and Phase Out abilities are awesome, and complement each other well, but its third ability (and I'm sorry but I don't remember the name) that is supposed to interfere with construction times I'm not so sure of.
How long is the effect of the interference? It's really hard to guage, and I don't think the skill itself specifies. Also, does it interfere with planet upgrades (i.e. population upgrades, tactical slots, logistics slots, etc.), or only the construction of structures in that system? The reason I ask is that, if it does interfere with such upgrades, there should be a way to tell whether or not that planet does, in fact, have an upgrade underway (progress bar on the planet, perhaps?), since this information would surely be apparent to the advanced sensor suite of a cutting edge geurilla war ship

. This also goes for Frigate Yards: there needs to be a progress bar to indicate whether or not there is actually anything being constructed. Without this information being availible, the use of the skill is effectively guesswork, whereby there is no real way to tell whether your precious anti-matter is being put to a constructive use or not?
Even if these progress bars (or similar indications) were availible only if a Marauder were in the system that would probably fix the problem at hand. As things sit now, however, I don't see a reason to take these abilities over others at all? How are we to know if the enemy is building anything at all? To have a skill designed such that its use is reduced to guessing is, in my view, a serious flaw, which is a shame, because the kind of gameplay the skill itself encourages suits my play style quite nicely.
Have I missed something, with this?
