Nice Hybrid build. Thumbs up. :) I also feel that Artanis fits as tankish bruiser.
I believe that Zelot charge is the best talent in the tier and Shield surge is worth taking only in case that you are loosing and need to defend and catch up in xp. Artanis deals damage primarily with auto attacks and need to be able to close the gap fast or he is useless due to his small attack range and slow speed. Especially since a bruiser needs to dive the back line not fight at the front and take damage. On top of that his trait is refreshed with auto attacks, and he has no escape mechanic. Similarly to Sonia, Illidan, Kerrigan... he has to keep attacking to survive.

Interesting build, I don't think it accurately fits the title though. Picking zealot charge instead of shield surge is a really weird choice, I feel like zealot charge is the weakest talent unless your team lacks a chaser. The omission of Force of Will at level 20 also really confuses me given the title of the guide.
