Though I see no mention of a Defense or HP increase, which means we still have over a thousand less HP than most Warriors, and about the same Defense as them. We also don't know if these are full or partial blocks. It could just guarantee a block, but not 100% damage reduction. TP generation will most likely still remain terrible.
I'd rather they go with more substantial changes than slapping an immunity on 33% of the time and calling it a day.
