Raven Lord Farming

I have a bit of a question.

Say I have a druid with swift flying form. If I group with another character, summon Anzu, and then log out of the druid (so the druid doesn't get saved), I should be able to summon Anzu multiple times on the same druid.

Is this allowed, or is it against the rules somehow?

I tried it long time ago but once I summoned anzu, that toon no longer able to summon it again until id reset. Things might change though.
