Yea, the initial d10 waves are too small now. It's a tricky thing, though: if you don't have auto-AIP on, and there isn't anything skewing the first wave to be harder than the second wave, there are basically two possibilities:
1) The first wave is survivable, motivating you to not increase AIP at all for a long time until you build up.
or
2) The first wave is not survivable, and the game is over.
Of course, there is a spectrum between those two where it's fundamentally all 1) , but feels different psychologically because you're having to fight and scrape to survive but can somehow manage it. And I think what we're targeting is the harder end of that spectrum. You'll still wind up playing a 0-AIP game for a while if you want to survive, but I'm not sure that's avoidable on 10/10.
Anyway, what I'm thinking is having Diff 10 games start with 20 or even 30 AIP instead of 10. That's kind of like the old wave size floor but it's more transparent. Thoughts?
