Boz I didn’t say that at all. Having people put words in my mouth as a way of forwarding their argument is somewhat frustrating.
CH will always do the heavy lifting.
However Tier 2.5 adds 5% resultant HP/sec to Rank 1 CH, and sub 10% to Rank 3 CH…that’s it!
It only achieves those values because you are sacrificing over 200 +healing to gain the set bonus…because it also forces you to use TS wrists.
You will cast faster, however you will lose over 300 HPs per cast.
My main contention though is its not needed for any content in game.
Battleguard, as one of the examples you brought up, should cap at around 500 HP/sec from a Shaman. If its appreciably more then that, then others aren’t nearly carrying their own weight. A Shaman can heal 50% more than that with Rank 1 without the haste bonus.
And I also agree you should have heal assignments to avoid healing on initial cast…the rest is handled by its “smart” cast function.
My point was, in referring to the OP, is its sub optimal to be laser focused on Tier 2.5, when its not necessary, and hes playing catch up.
He is probably better off grabbing uncontested offslots to bring his +healing up, getting 3pc TS, fleshing out short term with 20 mans, and then prepping for Naxx.
Tier 2.5 is quality of life, its very strong HP/sec, but measured against content, it simply isn’t necessary by any stretch.
It’s considered BiS soley because of HP/sec, but Shamans already excel at that, they don’t need the 5% or 10% added to CH…because they won’t chain heal encounters that hard.
Don’t take my word for it, look at logs for Battleguard, no one is chain casting within 25% of 2.65s…let alone 2.25s.
There is only so much raid damage to go around, its a relatively static value based on raid comp.
