if you look at it.. then Ultimates and Savage is also casual gaming... when you get used to the stuff... it would be the same as doing the same variants in the Storymode setting in a figure of speech...

Or if you want to listen to it in another way... you just gotta climb the mountain first, meaning learning curve.

Why should I move my tank out of stupid when pulled wall to wall when I got skills to mitigate and get HP back and doing massive damage as a tank? There is no need as you are pretty much immortal as a tank towards it and a healer can casual spotheal it as well.
