It's been a while since we had a thread simply dedicated to this kind of thing and I'd like to see some ideas. The dev team seems to think just buffing our healing straight out solves this problem or will lead to doing so but it's fairly obvious that even at +60% healing that Chi Wave won't save a raid in a clinch moment nor will it bring us above 2-3% raid healing with a decent healing comp.
So what would you add instead?
Format:
Chi Bomb
3 minute cooldown
3 second cast time (regardless of haste)
Draw chi from all party or raid members within 40 yards and create a chi bomb above your head. After 3 seconds the bomb plummets to the ground 5 yards in front of you healing all allies within 45 yards for [X * number of charges from nearby allies] divided evenly among all targets and dealing [(X * number of charges from nearby allies)*0.5] damage all enemies within 40 yards divided evenly among all targets.
Intention is to essentially make a Chi Burst that hits all targets within a circular range like Tranquility. Assuming you're in a 10man raid and it was gaining 40k per charge, you'd output 400k heals in a AOE burst and do 200k damage to the boss. In a 25m if you managed to get everyone it would do 1,000,000 healing and 500k. This is small enough damage to make it not worth using on a single-target for damage and a significant waste to use on AOE as it divides by number of targets. Pre-casting this just before something you know will do tremendous damage is similar to hovering over your Revival hotkey.
