Tasha's Rules, while they can be used for min maxing, also means they can be used for creating the exact character a player wants to do. If I want to play an Smart and Eloquent Orc Wizard now via Tasha I could without having my INT dropped to 12-13, as before that -2 to Int would make him effectively worse off in the party and therefor only "effective" ability score wise if I am rolling stats and get an 18 that I can downgrade to a 16. Power and role play often need to be balanced or in line with each other. That isn't to say someone couldn't have played an orc wizard before and have both fun and effectiveness, but with Tasha's it is now easier for us to craft characters specific to us. There are other ideas this enables like I could play a very not charismatic Tiefling Artificer or a Dexterous but physically weak Dragonborn Rogue without feeling like my Ability scores do not reflect my character. It allows players to fine tune both their strengths and weaknesses.
