A "tell me when to block" addon

[indopan]

So I'm a mmorpg player that has ventured into some common online games like wow, swtor and rift who tried 2 of the past eso betas I found that the concept of blocking attacks as a form of melee and ranged defence seems kind of mandatory and also something kind of foreign to me. It seemed difficult to determine when the best moments to use block and when the best moments to attack were. From what I've heard the developers talking about it seems like they are making it a key part of combat. So an addon that would basically spam some message telling me to block enemies power attacks when they're coming in (and probably an addon telling me when to interrupt enemy spell casting) would be at the top of my wish list to make the combat properly playable.
