Imo the issue is how much better than other classes in their niche are they.
Imo a lot.
When 3e came out they had a strong lobby group, same as 5e
In that "single target melee Nova" niche they can't be beat. The Big Paladin lobbied hard to make Paladins the Kings of SMITE!.
They and the Bard lobby got their money's worth.
I wish the Ranger lobby was so organized. But we all want different things and half our gold goes to funding different genocides. More Demonbane arrows, you fools!
