If you can only cast 25.5 spells in a minute instead of 25, you can also say that a speedless build only casts 24 full spells in 58.8 seconds where a speed build gets 25, the fact remains that speed = more spells in less time.
Have to dodge? Scathe as you move.
Mob is away/invulnerable? Time a freeze/blizz2 to land as it repops.
Take any time of not-casting, and turn it into casting - naturally good advice always, but it's even more meaningful when weighted into a spellspeed build.
If your playstyle doesn't support that, gear for it, but don't argue best stat != best stat
