The funny thing is I was just thinking "Y'know, Clerics probably never should have come off of WIS". Like CHA thematically make more sense, and INT could also work, but like WIS? Really? It just doesn't work with the pantheonic nature of D&D deities. When Clerics were just Clerics of all gods I guess it worked. However it seems wild and silly that a Cleric of say any of the Dead Three, all three of whom are Jackass-level clowns of gods (which one is Bam Margera and which Johnny Knoxville though?) should use WIS as their score. If you had the slightest bit of wisdom or common sense you wouldn't be worshipping any of those gods! Or Cyric for that matter! Or even some of the "good ones"!
I honestly think D&D, 7E or whatever we call it, they need to consider making it so most classes have a choice of primary attribute, because then you could do so much more with each class. Clerics would genuinely be better if you faith ascetic WIS Clerics, evangelical/charismatic "Praise Torm!"-type CHA Clerics, and thoughtful, bookish, Augustine-style INT Clerics and so on.
