the only way I can see it working in a telegraph system is on a fairly long cooldown where you are able to block certain big attacks once in a while to strategically minimize the mob moving around in a group situation. So that for example in a case of a tail swipe or breath cone mob, where players often have to move out of the way of a telegraph, and move every time the tank has to dodge out of a telegraph, the block ability would allow the tank to stay put a little more often. that or crushing blows + shield block, but I don't think that is what you are getting at. i miss that mechanic as a tank, though I don't think it would fit into this game too well. or any game with stalker like classes. through i guess the stalker could have a similar dodge type ability .. but that begins to feel too homogeneous where everyone has the same ability with a different name.
