Gift of Hedone: Speed Stat - How would it work?

Hello you lovely deviants,

I wanted to take the time to discuss the "Speed" Stat

Right now, I don't actually have a speed stat implemented, but wanted to potentially discuss how I would implement it.

What would it potentially Effect?

The plan is for this to effect your Movement speed and dash cooldown and basic attack speed. (not abilities)

The plan is to handle Ability speed and cooldown primarily elsewhere, but your basic attack speed may assist with cooldown, and I will discuss this later.

Overall Speed stat or Sub-speed stats?

What I mean by this is if we just have a single "Speed" stat that includes all the above mentioned (i.e. one Speed stat that controls dash, attack, and movement) or, have dedicated speed stats for Movement speed, Dash Cooldown, and Attack speed.

Which do you prefer of the below?

Option 1:

Single speed stat that includes (Movement speed, Dash Cooldown, and Attack speed)

Option 2:

Individual Stats for Movement speed, Dash Cooldown, and Attack speed

Option 3:

I did not discuss this, but you don't care about a speed stat or need for a speed stat, just let the subclasses having dedicated move speed etc.
