The problem with this idea is that for one encounter a day you're no longer a defender. You're turned into a mediocre striker or controller. Maybe a Leader if you're a LifeWarden.
I'm not going to go on a rant about defenders with defenses that are too high. I'll just say that defenders should be a viable target for enemy attacks. That's why they get so many HPs. Wardens more than most.
Conversely, if you're not negating hits in some manner, then all you bring to the table is a higher healing surge value.
