You know instead of buffing us op healers, why not just nerf Sorcs?
Imagine a TOR universe where a sorc AoE only heals 4 people within 10 meters, and bugs at the perfect time to only hit 2 of the targets. Have them need to channel a useless spell to recover 5 focus.....only if it crits. Oh, remove the sorc shield, the armor buff, reduce focus to about 300, and let's see what happens.
