Well,I have to agree to the OP a little bit even if its hard to me.
Why?
Because Im a trader since beta, I did a hard way to get my money in open. I get interdicted by NPC, but they are easy, no problem to escape, boring.
But interdictions by Cmdrs are a good nice challenge. Sometimes I escape, sometimes I drop my cargo by request ;-), and sometimes I loose my ship and my cargo because I thought I could escape.
But thats ok, thats the game, every credit was hard earned.
So, my fellow CMRD getting his money from solo and changing to open had not that challenge. In my eyes his money, his faction standing is not the same as my one.
He played another game.
Heck, can I transfer my money from diablo to Elite everytime I login, why not? Would that be a problem for you? Its the freedom I enjoy the game the way I choose...
Fine, you had a long day, than stay in solo and chill there. If you want a challenge than fine go in open.
But whats the problem, really, whats the problem to create a seperate Cmdr for solo and open?
