Well, some of the most used mods in MP (Worthy Heroes, Throne of Heroes), make national heroes very worthy. It is a nice step towards making the Luck/Misf scale less of a no-brainer
Also, some nations seem to benefit more from a Turm3/Luck3 approach than an Order3/Misf2 one. A handful of extra random gems are good to diversify, and the chance of up to 3000 gold in a turn can be nicer than a constant cash flow if you're not extremely troops-heavy (even if of course gold is always convenient, even just for more temples and labs

)
PS there's no pie in the sky. Just a teapot
