the reason a games balance patches can never end
1. perhaps unit imbalance gets found and perfected over time slowly unearthing the best units and the risky units
2. perhaps developers become reluctant to change units only to have to revert it later
3. is it better to buff or nerf units
4.?
5. maybe these are always better then these:
.krow rush > newtons + quake missiles rush
if only quake missile affected huge area
if only newton gun also slowed units its hitting
then they could keep the cost.
but newton could defend themselves better and quake could make cost vs terra
edit: .. buffing quake means buffing bertha =/
hmmm umm thats not good
