Gamers generally want more room on the desk so their mice can travel further without needing to be repositioned.
I love having a numpad for extra keybinds in MMOs and for number inputs for work, but I’ve since switched to a TKL and never looked back.
I still miss the numpad but that thing can be bought separately, and not smashing my mouse into my keyboard is a big plus.
Looking into upgrading to a Wooting 80HE once that launches; it’s like a TKL that wants to be questionably special, but given Wooting’s reputation I’d wager it’d still be better than anything else on the market.
