The problem is more than the elf stats, it is the flavor that gets baked into the elf mechanics.
For example, rather than a race of powerful mages − bards and wizards − now the elves are mediocre mages and moreso a mundane ‘lissome’ creature, highlighting mundane Dexterity as the defining elf trait. Any residual claims of potent magic, and charm, and songs, and poetry, from previous editions are in 5e a joke because in fact, the elf is average (+1) or below average (+0) at all of these things. There is little love for the elf, and 5e designers willfully turned the elf into a joke race.
And it isnt just the baked in flavor, it is the corporate branding that from now on − for legal financial corporate reasons − all future books, settings and player guides, will refer to the elf in the same way.
So now, not only did they destroy the charismatic (artist bard) intelligent (wizard) elf, they have destroyed the name − faerie grey elf, sun elf, eladrin elf − where these options occurred. So there is literally no room for these options in the core rules with the default world.
Destroying the kind of elf that I cared about is a sign of a bleak and unappealing future of D&D 5e. The direction that the future of D&D is heading. D&D 5e has turned the many editions of D&D into something that there is no room left for me to enjoy.
And worse even still. The 5e designers have aggressively opposed the D&D culture of character customization. So that races have paltry design place to customize, distinctive class features often dont come online until level 3, feats are scarce and painful choice, and often defacto unavailable until the highest tiers. And so on, there is scarcity of design space for customization, nevermind whose support for it in rules-as-written in the Players Handbook are muted.
And because of the decision to make *one* multiverse include *all* of the official settings. This unwanted flavor will persist and worsen as they are already baked into the the rules as written, and all future rules will refer to them.
For me, the designers have destroyed the part of D&D that I had enjoyed for many years.
