This might seem like heresy to overkill purists, or it might be to ponderous a code change, but you should be able to teleport between multiple bases by entering the co-ordinates once. So if your in a level one base and want to get to a level 5 base (and you have bases in range, in between) you just type in the level five co-ordinates and your there. The 1,500 crystals per trip between bases can stay in effect, so a trip between five bases would be 6,000 crystals (five bases but you only teleport 4 times, for everyone who was about to tell me my math sucks
). It's a pain to type in the numbers constantly, and in the current days of item cloning it favors boring AFB play over cool level 5 killing and selling.
