Healer job design in general has been completely abysmal from 4.0 onwards. The 5.3 AST changes should come as no surprise to anyone who has played healer in this game for a long time.

The message from the developers is clear: Healers should not concern themselves with optimization.

As a result, I now simply do 8 weekly clears with my static and then log out and play a different game instead. Pressing one button a hundred times and hoping for better Crit/DH luck is not an expression of player skill in the slightest. Sadly, the current job design philosophy shows no signs of changing.
