Link Speed-Up Reward Duration to Age

[NokNokJoke]

I'd like to see the duration of speed up rewards from chests and other bonuses linked to age. A 30 minute or 5 minute speed up is useless at Atomic or above. Why not gradually increase the lowest speed up at the higher ages so that Atomic always gets minimum reward of 6 hours, Cold War 12 hours and Space 1 day. And so on down the ranks.

it kinda is indirectly linked. it becomes easier to play at higher leagues as you progress through ages, and higher leagues give you better speedups
