I like having a small guns character to play with, but also a buffed-up Unarmed character to use too, for fun, not to be better than everyone else. Yes, having a 300% Science/Repair crafting alt is a problem for balance, but a lot of people just like having multiple characters. Game mechanics will hopefully be altered some day to make it so that having a 300% skill crafting alt, etc is useless, but not to make it so that you can only have just one character. That is just boring.
