Are you sure you are not forgetting which one is which? Without pics or video, id say its WAI and you just confused yourself.
Likewise, i can garuntee you dont want to change the way it looks or mark it by default.
I ignore the summoned vultures and lay waste to the main fleet.... if you give me a super clear indicator of which is a summon and which isnt.... you will remove the one chance that i waste my time on the wrong vulture.
You need me to forget, or his kit is not helping you much
