The 5-minute income needs to be removed.

[GooglyBoogly]

follow this time so the game progress can proceed faster. Nobody likes having to spend
14000 in armor upgrades just so their team can get titan and end the game.

I strongly disagree that the game needs to be made 'faster'
and since when is a titan required for victory?

Speeding up the game changes the balance of almost everything else.

Cooldown items/abilities become less effective, since they get less uses.
Slow tanks become weaker, since the lost time in moving around is worth more.
Creeps become weaker, since there are less waves.
etc....

If your argument for changing the income timer is solely to make the game play faster, then you are out of luck.
Speeding up the game, while keeping everything else balanced required more than 1, 2 or even 5 changes.
