Okay, try #2 since the forum doesn't like me.
On the box descriptions are a bit flawed. And no one uses the Antorak unless its a big map, they are dominating, or they know how to micro the ever living piss out of it so it doesnt get blown up by a stray piece of dust.
And yes, Vasari, after a long expensive series of techs, can jump all over the place. But thats mobility, and only helpful if when you get there, you can beat the fleet waiting.
guerilla warfare would include:
-Faster pahse jumping (this is an artifact, but would certainly fit Vas)
-Less AM lost per jump(this is a tech, so good)
-Either fast cooldown times with medium/weak damage, or slow cooldown with huge damage. (no, except nano-ish, or planet drain. Phase missle storm isnt bad)
-The same, but for regular weapons (nope, im not seeing high DPS or for any Vas ship, compared to its TEC or Advent counterpart)
-Traps (nope, mines are worthless to anyone with any intel at all. This irritates me, mines say "in phase space" but are visible without effort, just not destructible. This is ridiculous, if they are cloaked, make them invisible or undetectable until scouts actually use "see mines", I know its possible)
-Cloaking or camo (only Illums have something remotely close. Vas scouts can shit into phase space... which does absolutely nothing)
-Disabling (there are a good number of these techs in the Vas tree and fleet... however I might note that everyone has at least a few. Also that Orky has none... which is weird actually.)
Geurillas are typically fast, cheap, and sneaky. ONE of those covers VAS.
EDIT: So Vas is really, more guerilla-ish, but not totally. I think making a good cheap/weak/powrful unit (skrim) would be much more helpful.
