I will describe a situation happened with me:
Me was reraiding Takhisis. Swinged accidently my copper follower.
Fled. Look north - my copper ex-follower is there near savage dragon and not going to track me becouse other area it is...Ok.
So to return Solamnia code i should start OOC sh*t ( recall, quit, relogin, reraid) that i do not want to do for sure, or go north and continue doing my Main duty - reraid! But mad copper dragon is waiting there for me and attacking! Sure i have two ways slay copper then savage or start OOC sh*t.... I have choosen RP, and lost abylity to summon mettalic dragon.

And who is saying, we have RP mud here?

Everyone knows that Solamnics often attacking their mount while reraiding or ranking in moors or elsewhere with dragons or draconians foes
IR reasons: everything can happen in battle and your weapon can hit sometimes your metallic friend... it is all fine sh*t happens.
OOC reasons can be diffirent: drunk, hurry and so on...
I can understand that Dragons are wild noble creatures but it is too much... Current dragons just force players to break RP if sh*t happens.
So the idea is to make metallic dragon non-agressive mob if Solamnic accidently attacked it.
