It's amusing watching the Spell Caster Supremacy League turn in on itself, usually they are only roused to action when the fighter gets nice things.
Er...I mean, I wouldn't consider myself a Caster Supremacy League member, seeing as how I have consistently fought for reducing the power of spellcasting, developing non-spellcasting versions of classes like Paladin and Ranger, creating "simple" casters to parallel "simple" martials (and "complex" martials, like Warlords), giving Fighters more nice things especially outside of combat, etc. I find that this is less Caster Supremacy League infighting and more Wizard Supremacy League not being the entirety of people who like playing spellcasters. (Sorcerer is one of my favorite classes, alongside Warlord, Paladin, and Bard. I have a
thing for Charisma classes, for various reasons.)
By far my favorite edition of D&D is 4e, if that helps? It's hard to be truly caster-supremacist and like 4e.
Oh, I see people mad about it here and there - there are threads I've seen where people make the claim that it isn't fair that a wizard can go to sleep and wake up with whatever spell the sorcerer used to win the day. Like, person - that's the class feature. It's what Wizards do.
It's bizarre because their love for the sorcerer class basically has nothing at all to do with the class mechanics and is entirely based on the no-schoolin' class fluff. Fluff for classes is as thin as cheesecloth in 5e though, so it's bizarre.
Oh there have absolutely been people mad about it on all sides: pro-Wizard/anti-Wizard, pro-Sorcerer/anti-Sorcerer, pro-SV/anti-SV, all of them have had people getting their jimmies
thoroughly rustled. I just find it terribly sad that people respond to a
completely optional rules variant failing to appear officially in the game with "Ding dong the witch is dead!" and "REJOICE!" That is not "our team won the sportsball game," that is not satisfaction that good design won out, it is
revelling in the fact that the other side lost. It is "and GOOD RIDDANCE to BAD RUBBISH."
