Its all relative. You need to be able to calculate both teams money based on the kills each person got in the first 2 rounds, and what weapons you think THEY have. It's not hard to know what's the best course of action and guessing is not how you play CS. If you got decimated 2 rounds and they barely lost a player then you shouldn't buy 3rd round because you probably can't afford a full set of Gun/Armor/Helm/Nades, and half buying is stupid. You are basically giving away rounds if you think only a primary weapon and nothing else is suitable. Also, this is why you have an In-Gam leader, they are supposed to be doing the thinking and choosing for you. They are supposed to be keeping track of economy, kills, deaths, positions, etc and they ccann the strat, whether you should save your guns, and whether you should go for a clutch or not.
