Well-written guide, and most of your information is pretty good. One thing that you seem to be mistakenly building around is that the level 1 trauma trigger shield that you get is untalented. Thus, level 16 inoculation does not buff your trauma trigger shield.

I think this opens up some more options in your build, at level 16 you could go shield sequence, which allows you to get a free shield within three seconds after using your shield, effectively doubling the amount of damage reduction potential, or allowing you to spread the shield across two teammates. I was doing this last night with Butcher and Illidan on team, and it worked out really well.

Just a thought! Good guide though!
