That's fair if it works better for you, and yeah, the old school method is more common in Japan still, but WASD became the standard for several reasons and you made it sound like your personal preference was automatically superior just because you like it.
WASD is less awkward for your wrist, and it gives you better access to hotkeys. Plus, for the same reason that you find it awkward as a left-handed player, most people find using the arrow keys awkward. The arrow keys on laptops are also wildly inconsistent in their sizing sometimes, so they'd be awful to use with certain layouts, whereas WASD are always the same size and orientation.
Just watch how you phrase things. Your initial post could have simply requested the alternate keybindings as an option, but instead you just insulted the industry standard without presenting any kind of alternative.
I had to ask to get the constructive part of your criticism out of you.
