When activating manaward/wall there is an absurd delay between activating it and it actually doing anything, I was in T8 today and I activated it to step on a mine. I stopped, activated it, waited a second then stepped on the mine, but it didn't register that I'd used it yet and I took full damage.
This coupled with the fact that we can't use our abilities while casting spells makes it extremely difficult to time the use of these moves effectively. Can something be done about this delay on these moves? If not could the duration be drastically extended to make them something we can simply use on cooldown and they'll still be up when something happens that they can absorb?
