Looking for a viable build
I guess not?
Actually there are some bunky/support builds for warriors.
I tried out 2 that were actually working nicely.

This one is more of a close point holder (or you can try an early rush far than then let him hold there), its probably the hardest build to take down in a 1v1 cause its very high hp and its extremely high armor (3480 + 170 from banner + 100 from thick skin +400 while reviving)
The next one is better for supporting teamfights at mid, with shouts healing allies.
