When you upgrade a tower/trap/aura all the corresponding Tower Stats (Tower Health/Attack/Radius/Attack Rate) are upgraded by an exponent of 2.
So 1st upgrade will be 2^1 or +2 to tower stats.
2nd upgrade: 2^2 or +4 to tower stats.
3rd upgrade: 2^3 or +8 to tower stats.
4th upgrade: 2^4 or +16 to tower stats.
5th upgrade: 2^5 or +32 to tower stats.
Most people with Huntresses/Monks put many more points into Tower Health and Tower Attack than the other 2 stats. So let's build an example character.
Tower Health: 200
Tower Attack: 300
Tower Radius: 100
Tower Attack Speed: 80
If you upgrade an aura with 5 upgrades, here are the example stats for that particular aura:
Tower Health: 200 + 32 = 232
Tower Attack: 300 + 32 = 332
Tower Radius: 100 + 32 = 132
Tower Attack Speed: 80 + 32 = 112
As we all know, adding stats into a character (wether it be Hero Stats/Trap Stats) is also exponential, ie. there's more of a difference between 100 - 120 than there is 300 - 320.
So according to this example we're "improving" Tower Attack Speed "faster" than the other Tower stats. So proportionally Traps/Auras will fall faster because you're adjusting the Tower Attack Speed higher than any other stats.
