Make base towers replaceable again.

And yes, I do miss the late game, that's why I made this post

Again, the main reason the Devs chose to remove tower-HQ invulnerability was because it made the defense/siege needlessly long and lopsided. At the time, I think this was the most viable solution to deal with the problem. If you can think of an idea to balance it - without having players to deal with the "stalemate" scenario above - then I'm sure the idea would be taken into consideration.

Until then, if you're looking for longer games that transition to the late-end-game, your best bet is to look for a Btanks clan. Prog listed quite a few of them. The other hope is to wait for a new fast mode that increases the rate at which gold enters the game - but I think that idea is way back on the to-do list and collecting dust. :?
