Do YOU think we'll get a new Tank and/or Healer in 4.0? And vice versa.

They do not really need another 'me too' healer as introduced in HW.

What they should look at is reworking the Astro to move it away from WHM, adding more differentiation.
It uses the core abilities of the whm - and as such will always be thought of as a semi-clone of that class.

Restructure the N.Ast to make it more individual, allowing some melee abilities aided by shielding.

And, get rid of that card rng gimmick - it is a gimmick, put there in an attempt to deceive players into thinking there's more to the class than just an whm with less utility.

No class should be reliant on rng to decide what ability it uses. This isn't a lucky lottery game, healers play a vital role in group and raid healing and shouldn't have to deal with roll the dice ability mechanisms.
