Just a quick idea : instead of completely erasing them from 1.11 how about making units something like 10% more damage/hp/armor + 5% magic resist at 10:00 game time, 10% and 5% more at 20:00... etc ? It would lessen some of the "glass spawns" effect.
Ofc it's just a vague idea so don't bitch saying ZOMAGADZ BUT AT 2HOURS DEY WUD B AMBALANSID !!!!
