Bear Build Ascendency question

Hello,

I've been Stuck in analysis-paralysis for 2 days now and need (professional) help.

I want to play a bear build, I like mauling and slamming with that, but I don't know which class to take. I've seen builds with Smith, titan and shaman, but did not really get what they are best at.

I like tankiness, life regen and a slower, more methodical, harder hitting approach. My only other character was a shieldwall build. I don't need to Zoom like hell.

I think the constant rampage stuff even for Single targets is Kind of odd, I'd like to hit my enemys, at least from time to time. For mapping it's fine though. I also have no clue what that rage or glory stuff is about (i know the skills it works with, but have no clue about the "feel" gameplay wise).

Which one would be best suited for me?

Thanks a lot in advance!
