OP here. The majority of these issues if any of you go back and read is how each healer feels awful and boring to play right now. If potencies were buffed through the roof, it won't change that as you are all fully aware. That is not to say potencies are a none issue, but its lesser compared to the feel of the job.
Remember how in HW people still played Astro when it was undertuned and Whm when it wasn't meta? But in SB everyone abandoned whm because it got reduced to being the first pure healer?
Its because they were fun even if they were weak in the former. The latter was not fun in the slightest
Fun>balance because ilvl tends to make up for lower parse numbers.
