Many abilities? Try maybe one or 2 of the abilities that were capstones. I don’t remember ever having to spec into healing spells like rejuv on my Druid - I just had them baseline and learned them from my trainer. The talents improved these baseline abilities. Swiftmend and Nature’s Swiftness were the only talented abilities in classic. Wild Growth was added as a capstone in WoTLK, and Tree of Life was added as a capstone in BC. I don’t call burying Innervate at the bottom of the talent tree locked behind ursol’s vortex or mass entanglement a win.
How it used to be was the level cap increased, and we were rewarded for hitting that level cap by getting a new capstone talent. A new fresh ability that made hitting the new level cap exciting.
