Yeah the values need to be adjusted, but then again because it's so bad gear might weigh those as fairly cheap so you'll end up with +4 and +6 when it should be +3.

With 2 points total from gear I am getting an extra 20 Magic Armor on Lohse. Then again my Lohse is also decked out in 262 Magic armor before buffs. After buffs, 2 points ends up yielding an extra 40 magic armor which is almost enough to cover one tick of environmental damage.

It all depends on gear and what other abilities are out there. So if I spent 4 levels putting points into magic armor and stacked it with my current gear I would have 85 extra buffed at 6 points at level 8. That's not bad at all.
