well, when you have 20 minute NR games on mucho money maps, skill becomes less and less important, and the winner is going to be determied by who picked the right unit to build copious amounts of
having played my share of money maps, i'd have to disagree.
there are still limits. there is a MAP MAX, there is a Race max of 200 points and the time limit so you have to choose what to build and what to upgrade.
air has mobility advantages but is significantly weaker firepower than it's ground counterpart, goon vs scout, hydra vs muta, golaith vs wraith.
scout is probably the most powerful of the cheap air units.
also, it depends on how they built Defense and how you choose to attack that D.
anyway, in my opinion, u haven't played very many money maps. you don't see the intricacies of it. u just see the intricacies of dealing w/ limited Crystal and Gas resources. there are other limits. map limits, race limits etc. therefore SKILL IS IMPORTANT.
