Please close the loophole in the doctrines...

In one regard that seems even more important for multiplayer games (vs humans aware of that loophole) than those against your AI, which currently seems not focused on it...
...the current doctrines are a step backward compared to the situation before -- sadly in a way that defies common sense

Before:
We only had the "fixed doctrines" assigned to the fewer existing ship types and all of those had the "unclassified/support" types last in their target lists - or at least way behind...
Result:
It was easy to defend for example a colony ship -- just put anything with decent damage and survivability to accompany it and you were set

Now:
You can have special ship types to attack unclassified/support types first, even to the point of being sort-of kamikaze, i.e. ignoring anything else.
...there seems no sufficiently working counter to that as long as you don't add some sort of "protect ..." rules into the mix that overrule the "normal" target order - in order to protect what you want protected!
I.e. you have to know the enemy doctrines and class-mix in order to design a working doctrine for protection - that is absurd!
It is just common sense that any escort ships are there to protect those colony ships, for example, instead of working down a priority list depending on size or type before considering to just fire on whatever targets the very valuable undefended thing they are here for!

So - to me it seems the easiest solution is to add some sort of "protector of xyz" (in my book, unclassified/support would be sufficient to have as only entry there) into the doctrine's list?!
