Game Mode Idea: Growing Strength

Ok, so before I talk about this idea for a game mode I'd just like to say that this is well... an idea for a game mode. I know that this section for DotaFire is for Hero & Item Ideas, but I honestly couldn't think of a better place for it. So, without further ado... GROWING STRENGTH!!!!

So this game mode would start similarly to all pick (or captain's mode if a variant of it were to be made). After the game starts, ie. the timer hits 0, the game mode would officially 'begin.' The main difference between the game modes is that towers have 100hp for tier 1, and 300hp for all others. The same goes for other buildings, they all have lowered health. However, for every in-game second that passes, buildings gain 0.5hp. Also at the start of the game, creeps are worth more gold, saaaay ~500? But then every minute that passes, the bounty is lowered by 50 gold. Speaking of creeps, the creeps' hp will rise overtime as well, at a rate of 50hp per creep wave (or every 30 seconds.)

Obviously, these things would need some cap, I'm open to suggestions of what those should be. :D

Thanks for reading guys/gals, please tell me anything you'd like changed about this and vote up in the polls what you think about it! :3
