Importance of Range: Explained

[JPA32]

my defences are 16,000 archer towers and 1,000 rockfalls and this along with troops will keep the invaders out, traps suck, and so dose all the other defences, it takes around 4 archer for each archer tower. you want those, if you got traps all the guy dose is send in a very replaceable amount of wariers. turst me.

Traps and Treb's are both triggered by Warriors spamming. Since they both have 5k base range.

Traps take up less space and allow for more archer towers to help defend. So they are essentially better.
