Looks like the diffeence in the two posts are the difference between tootip data and actual combat damage.  There's no way different combat calculations have made it to test yet.  that's just not teh way Vanguard works.

And honestly the issue isn't whether you're getting a +200 or +300 +damagemodifier.  It's fhow many times (and when) that modifier is being multiplied.  In that case Fujis. calculations provide the best insight.
