My Crusader play stile is built around the buffs that executions provide. I have invested in all of the skill in the Execution tree and I am hardly able to execute anything right now. I have noticed that if I just let the timer over the head of the mob expire, it stands there while it ticks down but if I press 'F' in an attempt to execute the target, it will explode immediately. About 2% of the time (very rough estimate,) I am actually able to pull off an execution.

I've considered re-rolling and just forgetting about executions. It was a viable play style but with this current bug, there are other perks I could be using at my level. I guess I am glad that it's not just me. I suppose we'll just have to wait around for them to figure out what's causing it and then fix it. [shrug]
