No comment yet on the increased waves thing, but I'm going to record what I see in my current game as an FYI thing. (Watch for edits to this post, and comments once I wrap up.)
All waves include the "1 starship" aswell, but I'm not writing that down everytime.
On Diff 8 Vs a One-Way Doormaster and a Bully.
The indicated gametimes are when the wave alert spawns, not when the wave arrives at my system.
AIP10, 00:14:20, 82 Bombers Mk I, 50 Teleport Battle Stations Mk I from the Bully.
AIP30, 00:28:08, 94 Fighters Mk I, 79 Snipers Mk I from the One-Way Doormaster
AIP51, 00:36:26, 398 Raiders Mk I, 167 Fighters Mk I, from the Bully.
AIP51, 00:49:52, 68 Teleport Battle Stations Mk I, 94 Frigates Mk I from the Doormaster.
And then the Roaming Enclave blew my home command to pieces.
Overall, I can't complain about the waves at all, they seem okay to me.
Note however that I never got more then one hop away from my home system, I was always able to bring my main fleet back to support my turrets. I expect that once I get 4 or 5 hops out the waves would become more of a threat.
Going to reload and see if I can survive this Enclave somehow.
D.
Edit: And nope, this enclave just rolls right over me regardless of what I do. Went and made a bug report, think they need a balance fix.
