I see no problem with the tele away, if you disabled tele while under attack then someone could be pinned down in a grueling and abusive curbstomp by chain attacks. ever think of that? the teleport seems to be a tool for escaping bad situations, so it sounds like it was used as intended.

On the other hand, having your army recall if your target goes poof sounds MORE than reasonable, heres two thumbs waaay up for recall upon change of target!

additionally, he could have just as easily used a truce item.
