You are living in a dream world where new armies and battletomes are perfectly balanced and fair. The General's Handbooks are VITAL to the continued balance and health of the game. We, as gamers, should be pleased with the direction that GW has chosen on this issue.
Speaking personally, the fact that GW is releasing regular FAQ's and the General's Handbooks is a huge part of why I have started playing GW games again after like about an eight-year hiatus.
