I was standing around a summon stone way out in UP where everyone takes forever to fly in and i thought for a second, wouldn't it be nice if Engineers had a "click buddy" so i could open a portal and click it myself and start summoning people? That may be one little trickery that could really help give some fun utility to Engineering.. I mean, after all, we're supposed to be crafty.
Just a thought.. if not a click buddy it could be "an extra pair of hands" or something unique so you could click your own summon portal at the stone
