After several ascensions, I can't say as the megabutton is useful. It is equivalent to tier the 6,3 button in terms of absolute value; but that button is automated, much faster, and two tiers below cap. It should start out better than tier 8, not worse. It takes 5 ascensions to unlock. And this is me having done 15. The linear growth of it through achievement points just doesn't make it worth while. An *eventual* pay off, several hundred runs later, isn't incentive.
The ascension bar is a bad mechanic. I shouldn't have to click something ten times to get it to work. The button (which doesn't currently appear) should appear with a single purchase in the megastore.
Most of the rewards upgrades are usless. Tier 1 x 4 when you're on tier 4 is pointless. It's an increase so small the $/s counter doesn't even increase
I still don't get what prestiging is for. By the time I can prestige Tier 1, all of my income comes from tier 6. Prestiging tier 5 when I have tier 6 going provided less than 5% increase in income. What's the point?

Adding a cash per second while in the shop, so always earning while away from the hack page, thanks for this suggestion
