Needs counterplay is what "not feel frustrating to play against" means.
Using a control ward or sight item for her W would also be "change the mechanics of the shroud slightly."
Different paradigm of buffing means "Compensation for counterplay she never had before, because it would nerf her even though it was healthy to change her this way."
Rewording using simpler text:
Change Q and E a bit to be better abilities in terms of interaction or effects. Reduce the Ultimates impact on Akalis overall gameplay. Change how her W works to allow counterplay. Doing this is basically a rework, so it will be pushed back until they can find the resources.
