When you are on your 87th pull on the nth boss of a raid, it makes you drowsy rather than fun.
For sure having most damage from 1 spell is common for most specs and its the reason ppl didnt like classes for all of BFA. But enhancement is the end of that spectrum. At least for other classes, you're trying to get to a point where you can use that ability by synergizing your other abilities and reach your goal (much less exciting than i describe but still). Our on the other hand. Stormbringer procs even off of auto attacks. And it procs constantly. I would love to work for a moment of big pay off like "enhancement disclaimer" points out for shadowlands but it doesn't seem within reach.
If LB is gonna hit less than our spam ability, it's just gonna feel like a filler when we can't spam it, with twist of msw "mechanic". But if it hits hard with less procs like a combo point system or holy power system, gives us way to decision making. Makes our new talents stronger AND becomes actually exciting.
