At the risk of sounding especially snobby, you can tell how much raiding someone has done by how much they value Deployment
One side note, Eye for an eye is a shadow of what it used to be
In terms of sheer numbers, I don't think SCH is genuinely lacking in any particular area, it's HPS and DPS throughput is there or thereabouts with only it's MP costs vs potency really standing out now.
However I do agree that the job just feels like a bit of a mess. It's akin to a big jumbled up bag of quirky cooldowns with little to no synergy between them, the fairy has been watered down to a shadow of what it used to be, it almost feels like it's something SE wished they had never implemented in the first place now which is just shameful IMHO.
I've said it multiple times and I'll say it again, SE need to get someone in the team with a good grasp of healing at Savage progression level, but also is sympathetic to casual gameplay aka the likes of levelling dungeons and 24 man. Let them go wild with the SCH and give it the rework it both needs and deserves, there's so much potential there to make it far more interesting and intuitive than it is now.
