I think we have to be careful suggesting anything that involves Avatar's Favour. A regain or powerful elemental magic evasion aura would be nice in theory but the mechanics behind Avatar's Favour are so intrinsically soul-wrenchingly awful that we're just making the job more boring for ourselves in the process. If it's beneficial for the aura to remain at full strength (which for a good effect it certainly would be) then, as summoners, we've just put ourselves into a position where we're not able to use blood pacts any more, to say nothing of the attack penalties. "AFK with Diabolos" is an abhorrent concept and I really don't want to see it getting more prevalant.

I do however like the idea of having a spirit as an "auxiliary" pet alongside an avatar; it definitely has merit, especially if you put new systems in place to make having that spirit out more interesting and, dare I say it, balanced. As I recall, Alhanelem has often said that it'd be a mistake to take the focus off avatars for summoners, which is something I can definitely appreciate, and a new system along these lines would work to that effect. I've cobbled together my own ideas for systems of this type in the past but, given the current climate with the developers, there never seems any point in making suggestions.
