(like a chest diagonally) I don't need them here.

What's the point of WATER anyway? To learn something new and improve your skills. "A chest diagonally" which caused the argument is not some kind of hardcore thing – it's the FUNDAMENTALS. And to say "I don't need them here" is the same as saying "Why should I bother with rushing? Only hardcore players do that" or "Why bother going on the snakes in the swamp?" These are also fundamental aspects of the game.

+1! IMO, it's in the second week that all the skill is revealed. Many (including me) simply don't know what to do in the second week when there is no clear plan.
