I had a long drawn out post I was halfway through, but honestly I'm tired of arguing this. The math on how all these buffs compare and the effect they have on dps and been done, and the verdict is that a 30 second +3% attack speed buff that can be cast every 1 min consistently beats out balance and arrow in real situations. This is not including the fact SCH can simultaneously cast a 10% dmg reduction field every 30 sec that lasts 15 sec.

I want to like AST too, so I get why people try so hard to defend it. But fact is it's just not that good atm.
