What are the opinions on Deathwing?

I came back to the game after a longer break and I really enjoyed playing Deathwing right away. It may sound dumb to complain about a champ that has such a decent power level and gameplay that I enjoy, but there is so much potential for more complexity to the champ that really tickles me when I think about it.

It feels like instead of having more interesting choices in choosing talents or choosing which stance to land with, when to change your stance or any of that he has just raw damage.

Already having +100% dmg to champions baseline makes talent choices that add some more % dmg on top of that feel less impactfull. Going to lvl10 feels like it doesnt give you much. Not even the lvl20 tier talents feel like they are close to having the impact they have for other heroes.

There are no quests, no requirements to have the baseline bonus dmg or to stack it up to its full potential somehow, no real incentive to ever change stances mid combat....

Is it just me that feels like everything about deathwing after the basic idea of the champion is too dull?
