On the Google doc we're ironing out MP costs, and the topic of temporary portals came up--or rather, the topic of just banning them altogether. I'm of the opinion that temporary portals (as in, spend 1MP for a one-time, one way ticket to somewhere else) are something that we're better off without, as they defeat the purpose of us making travel difficult and that they're a lot less interesting than spending your MP to make a cool steed/ship/chariot or a permanent portal like the Bifrost.

Any strong opinions?
