I don't know...haven't played with it but I liked that it was something I only had to worry about every minute or so, but I agree any big movement fight would really gimp you...but talents are going to be able to be moved around out of combat so that'll help :)

and luckily there are 2 other options that anyone who really doesn't like the rune can choose from...so it seems that Blizz may have done a good job with this tier :D

The shield thing looks pretty good to me. You're just gonna have to trust me gym, you're going to hate seeing those little runes on the ground if you spend any time with them. It's also completely useless in regards to any kind of solo questing, plus when you're on the move clearing easy trash from dungeons.... I'm just shaking my head here. There's so many ways that the "stand in your ground buff" thing sucks.

But why?! I want runic stuff! Please don't take it..! :(
It seems to me it's niche is fights a la Ultraxion, where you can't really be moving around. Of course, all 90 LVL talents are awesome for such a fight, but I'd prefer Rune of Power, because magic circle.

I'm with byronius_prime on this.

This Talent system, on a whole, is based on making the player decide what is best at any given time.

We have to remember, this isn't going to work like the current talent system. This isn't a 'choose once and foget about it until the developers tinker with your abilities in the next content patch' system, it's a 'looks at what you have to do for this boss and pick what is best for you' system.

Better yet, if you don't like Rune of Power, the other two work well enough that you aren't a big pile of suck for not choosing the best ability for any given encounter.

byronius_prime's example was Ultraxion, for example, however, note that you receive a lot of damage during that fight. Incanter's shield will work just fine. The decision there actually comes down to +15% 100% of the time or +30%

Someone can correct me on this if in wrong, but there is only one fight I can ever remember standing absolutely still on, and that was patchwerk. Even fights where you are relatively stationary, you end up scooting a little bit here or there.

Here's my guess: invocation for soloing and possibly more stationary type fights. Incanters shield for pvp and most other boss fights, including probably every heroic fight. The rune of power for the very rare occasion you'll be nuking with virtually no movement. Also this adds another ground effect to the ever growing list of ground effects.

Frankly I just hope they think of something different to put in there. I will say the rest of the mage talents appear to be shaping up into some interesting choices

Not up to Ultraxion yet? 0:
You don't need to move on Madness or Spine either if you pick a good spot to start in, except during times when you aren't actually doing any damage anyway.
