If you're doing him in 226/232 gear, then you're reffering to Herald of the Titans, not Starcaller.
To answer your question as you presented it; yes I have done Starcaller since 4.0.1, but I was in ICC gear. Did he hit hard? Sorta, but with good heals, and proper cooldown use it wasn't anything special.
In 226/232 gear, that may be another story, but again I think that puts a lot of pressure on you using the correct CDs at the correct time as a tank, and the heals being on top of their game.
TLDR: it doesn't seem any different to me.
Good and Evil are man-made words.
Death is the only absolute. Better the butcher than the butchered.
