First attempt: insufficient power to run even one of the various shields. Time to practice rushing skills...
With the right timing and without the power drain of the left, Omnis can get a foothold on the right if a few lathe-heavy and pre-powered ships are used correctly. Omni reactors is required. I had flaws in my timing, but it is probably possible to take the entire right with Omnis, and come back for the left at the end.
Playing in the seemingly intended manner, I find a huge deficit, regular attacks (which are largely irrelevant). With the starting force, I was able to take all of the Emitters rebuilding the left body of Struc, as well as the first line of Emitters, mire-spawners and ship-spawners (With the mines from the Emitters falling under my control). Thereafter, I had to wait an irritatingly long time for the fleet to recharge and for a few amp gems to turn up (Omnis, mine dischargers). I was surprised that the Omnis could get a foothold on the main landmass. HQ-dropping took out the Tortoise rammer (I was surprised by how effective it was at ramming, in point of fact).
One Discharger in the starting fleet was unhelpful. Also, the lag in the final assault became a factor.
Overall, interesting. It certainly forced me to use the (very) unfamiliar tactic of multi-rushing. However, I don't think I had a use for more than half of the fleet. If it didn't have three lathes or an MK7, it was left at the left and forgotten. (One or two port-ships were drained as single-use batteries in the initial assault).
Does anyone else find the Tortoise and the Hvy Miner to be the main workhorses here, with MK7s as defenders?
