Even as a main summoning can be annoying in dungeoneering as you can go right til the end without seeing a charm. It would be good even to just bind 1 charm so summoning can be used properly beyond a door opening skill.
I would say there should even be charms available at the table in start room. I don't understand why everyone is complaining about this players style of play. Players should be able to play as they like. It's one of the things that made runescape great which is the choice of focusing only on magic, range, or melee in one account if desired since it's beginning.
