Hey all.
Was playing League the other day and was thinking that I really like how when you are moused over your QWER, it emanates the blue circle from your body to show how far the range is on whatever you want to use. So I thought to myself "Wow, that'd be really useful on WoW, I see mages waste Frost Nova all the time because they thought they were close enough but they weren't." And I was just thinking of even more uses for it, like Fan of Knives, you think it will hit, but it doesn't, you've just wasted a chunk of energy. Personally, I think it would be neat to always see the range for Bladestorm since my main is a warrior.
But anyway, I'm not sure if an addon like this exists already, but if it doesn't heads up to anyone that would want to make one on their free time. I feel like a lot of people would appreciate something like that.
