Yes more time, but does that equal more skill? Being able to make quick decisions and micro your units on the fastest speed, also to come up with those strategies in the same time you could on ef is what makes it harder. That's my point you could slow down any game, take Super Mario Brothers 3 on NES, it would just make it much easier to not get hit by enemies. Take any Call Of Duty game, it would just be silly as you could easily shoot the other people. Slowing it down by playing ef or slower makes it easier for many people because they have time to plan strategies and its easier to micro units, but there are people who could play he same strategies and execute their units the same on fastest.
