Edit: Paladin Moderator Fhi kindly asked if they could quote this in a Class Beta write-up post and I am absolutely fine with that (and a little bit humbled :3) and if any others would like to then that's also awesome. Seems the next wave of patch notes will use a similar format to this so maybe that'll be better for folks.
I’ve separated “ability pruning” into three categories that have emerged predominant:
1. Removed entirely. (Removed)
2. Abilities that have been made Spec-specific. (Abilities Consolidated to Spec)
3. Passive bonus has been merged with the base effect of a spell or a spell was needlessly complicated whilst providing little to no gameplay has been consolidated. (Mechanical Redundancy)
These categorizations help divide the cluttered “pruning” section, improving readability and helping to clarify that many mechanics have not been removed but rather consolidated resulting in less shock at how much has seemingly been “removed”.
Some changes in the “pruning” section did not fit into the 3 categories and so I have moved those to a “Misc.” section and suggest that they be viewed more as actual class changes. I have not included the "PvP Disarmament" section or those changes here as I do not believe anybody is actually upset about THOSE changes beyond concerns of PvP balance and highly, highly niche PvE situations. Feel free to debate that decision, I'm not beyond folding those changes in too. It's just hella' tedious.
I'm sure there are errors. I'm sure there are typos. I'm sure you'll all happily point them out to me. I'll try to edit the corrections in without breaking it more. I think the formatting is consistent now. Hopefully this will better identify what is really happening to your class in one easy to read bite. I've no doubt much is still subject to change and I'll try to keep this up to date when the next wave of notes land later this week.
