I would rather not waste infiltration nades to demolish garrisons as their long cooldown period renders me unable to use them when I need them for something else. A price reduction for sturmpios and maybe a flamer upgrade would help okw's struggle against garrisons.
If you need oppnent to get out of garrison and never get it back, because it will be demolished, explain to me how is that wasting the cooldown again?
Also what do you suggest for USF then, who have same prblem?
