It's tiring to manually select their skill when trying to buff as many towers as possible before a wave starts.. especially when you have multiple forges or wells. It should have a simple hotkey so buffing towers manually is easier.
I'm glad one of my favourite (actually, more of my top favourite) tower defence map from WC3 is now in SC2
Just sad that some of my favourite towers from WC3 like monsoon and ice (not the one doing path damage) isn't here
