I detested the need to use the ability "Guard". I would have liked to have seen "Guard" turn into a mode of some sort - something like how "Defender" is now:

e.g. "Guard" - allows the chance to block incoming attacks. Attack power is reduced while guarding.

However, I'm happy with the shield/blocking changes announced in the patch notes. Maybe the Palading job will have more buffs/actions that are geared more towards shields.
