New to warrior/titan need build recomendations

hello!

I'm very interested in building a build with a power stack, a lot of health and a lot of blocks.
I would like to use weapom swap a lot, but I don't have a good idea about what to do, which skills to use, etc... I'm in act 3, and as it's my 5th character, I don't have much desire to discover things in the campaign.
Recommendations please?
