Well, firstly I have bound S, and secondly being able to move forwards with the keyboard is important if you want to click anything that can’t be hotkeyed, like a particular player, thirdly I have not lost Q E or R, fourthly my pinky rests much easier on shift when using WASD, which is why WASD has been standard in the industry since the late 90’s, and lastly the keybind A is garbage because it is a movement key and I don’t want to upend 27 years of muscle memory to move A to Q for no good reason, which I will then have to unlearn again in every game where S is actually a good bind, like DOOM Eternal, and because Polymorph is almost never used in most content - it is very much a a PvP spell on the whole.
This game may not be an FPS game, but you move exactly as if it were. Maybe if I compared with Skyrim, which also uses WASD, you’ll get the point? Who knows.
If it works for you, great. But it doesn’t work for me, and it won’t work for most.
EDIT: This is what I mean - you can’t fit it:
1234QWER = rotation spells → There are Nova, lance, frostbolt, flurry, glacial, ray, orb, blizzard, comet storm, RoF, bomb. Whoops, that’s more than 8. RIP.
Shift Q/W - DPS Cooldowns (Icy Veins) → Okay, we can do that. Now Freeze is far from Frost Nova, but fine.
Shift E - Big Defensive (Turtle/Block) → which one? Block? I guess?
Shift 123 = IMPORTANT Utility/Defensives, think stuff like Shift 1 for Alter time, Shift 2 for Ring of Frost → hmm… so, alter, mirror, cold snap
MB4 - Interrupt → Okay.
MB5 - Blink → what about blink back and movement while casting? We’ve got 2 buttons here that won’t fit.
ZXCV - utilities/CC → poly, dispel, nova, DB, knockback, cone of cold, shifting power… we can’t even remotely fit this
Where’d my racial go? Where’d my pots go? Where’d my trinkets go? Where’s my special action button? This won’t work.
