You should have went massive flak if all he was spamming was ilums.
See below.
I don't think Vasari flaks are what they used to be.
I agree with this 100%. I actually did turn out a huge number of flak - basically as many as I could. It really wasn't a match for the illums. I knew ahead of time it wouldn't be, because this is an old story (illum spam is all I ever see). But what else am I supposed to do? I mixed in some assailants in an effort to "mix it up a bit" and also counter his cap. But it was mostly flak, with not much results to show for it.
Upgraded starbases are no match for illums. Once someone hits the 50-something illum mark, the SBs go down pretty quick, even with hefty use of repair bays.
then have his Egg nanite the enemy cap while focus firing all Assailants on it.
Yeah, got one of his caps that way (he got mine too). He just built another. I didn't bother rebuilding mine.
Today, had another match with another "pro-type" (a recognized name on Astax's replays thread). He picked Advent. As the game started I sent him a friendly message and said "Hi, I noticed you picked Advent. Instead of just spamming illums, why not try to build other units to vary the game a bit?" I got no response at all, so I knew what was in store. Sure enough, he came with massive numbers of illums, a mothership, a carrier cap, and nothing else. I had already decided on a strat of "mutually assured destruction," so I had built a ton of siege frigs. When he jumped in with all those illums, I jumped at him with all the siege frigs and started taking out his worlds. He jumped back to defend but my siege frigs could toast his worlds faster than he could kill them. Then I sent some colonizing frigs while his illums were chasing down my siege frigs. Unfortunately for me, enemy culture was too strong to colonize, but my "mutually assured detruction" strat worked. While it insured that I could not win the game, it also insured that he could not, so he quit.
I think I'll use this strat more in the future. Don't get mad, get M.A.D. (mutually assured destruction)!
