GreyLord's suggestions were in terms of 5e rules.
You don't need to bring back d6 initiative to enable spells being interrupted, for instance.
You might see it that way but in 5e there is a thing called a Concentration check. The example you cited ignores that completely and the spell is lost. I'd say your example is more 1st and 2nd Edition and less 5e.
