I agree that 16 starting Cha for a bard is playable - but if 18 starting Cha is available as a choice, why wouldn't you choose 18 instead of 16? I think starting characters should be more-or-less balanced, rather than deliberately making it so that certain race/class combinations are more effective than others. Perfect balance is impossible, but that doesn't mean that one shouldn't try to at least balance out the most blatant effects.
I have totally opposite sentiment. For me game should be imbalanced, and power level varying heavy, but there should be enough useful stuff, even powerful character cannot really cover all the bases.
Agreed. I'm just pointing out that as long as certain racial templates favour min-maxing for certain combinations, the critique of "race essentialism" is going to have a certain superficial plausibility.
Certain mitigation of it, could be born from some dunno special feats that are allowed for specific options of class/race and so on.
But you know wokesters are angry because it's WACISM. People who are really into both VERY SPECIFIC CONCEPTS and MINI MAXING gonna be angry their concepts are not that mini-maxed.
I shrug honestly. -2 to Cha for dwarves gives you notion they are generally less charming and influential socially, and it's not nearly enough to make Cha based characters really really weaker.
Difference between minimaxed human bard and dwarven bard is 1 on roll. Considering how swing d20 rolls are, any mini maxing dwarven bard whining about how this difference make dwarven bard unplayable deserves boot.
Now we can discuss dunno -4 Int for pureblood orcs as real problem with them being wizards (because spellcaps). But if you whine about 16 in your primary at level 1 - you deserve to be wiped out from multiversal memory

I prefer that in a wargame, the system mastery should be for in-character choices during the game - not meta-game character creation. I don't want winners and losers based on who chose the right race for their character. Players should start out more-or-less equal as of character generation, and then tactics and system mastery applies for how well they accomplish things in the game.
If you play D&D as a poor wargame then you minimax everything to hell. If you play it normally, then you just don't care about lack of one +1 to roll.
TBH I can totally imagine wargame where you kinda roll your units, like some card games where you not collect, but randomize your hand and then deal with it.
