While i admit it does play very similar the difference is quite noticeable for WHM mains. I loved HW WHM even if it sucked. I liked SB WHM even if it still sucked. TBH i was iffy about new WHM. My abilities taking longer to cast(likely a change to base stats) and i miss my usual rotation but at the same time it feels more like a healer now than a DPS that can heal the odd time it needs it since its HoTs kept up with a lot of the damage alone. While the loss of Largesse is sad its not needed and tbh if it still existed it would make their last skill nothing special in their kit. Repose was useful in SITUATIONS that honestly rarely happened/useless skill crowding the bars. Lucid dreaming needs to be spammed now cause of the new mana cap and how much costs are compared to it but thats just something else to manage which is fun since before managing mana on WHM wasnt really a thing cause of the amount of skills they had that helped with mana problems. After some play time and adjusting i think its fun and thank god for the lack of protect that spell was useless in the first place XD.
To address your thing about "they keep taking skills away shouldn't they be adding more?" (Sorry if its already been brought up) but i feel like if anything its a good thing they are removing skills because we already have a ton more than needed as is so if they didn't downsize each patch we wouldn't have enough hotbars to fit all the Spells/Skills/Abilities.
