Auto-attack doesn't save for special weapons
I believe this was talked about in reference to Engineer kits once on the forums here, and an Anet person said they were aware and wanted to implement it when possible. It’s just not the easiest thing to do, apparently.

This is also the case for Necro Lich Form
Ah ok well disregard this post then.
I don’t think this post is wasted. At the least, it shows that this should be implemented for more than just engineer kits.
