Re: I paid 15,000 for Luke Skywalker. ONCE IS ENOUGH!!

That was to unlock the ability to play him and any other upgrade from a standard soldier by use of battle points, which are completely different from credits as they are points used during the round they were earned in. If it worked like you want, everyone would be fighting to be Luke (or whoever else) from the get go.... And you'd pretty much never get to be Luke (or whoever else). There has to be some way to make it take some effort. In SWBF1 we all played over the last 2-3 years, you just had to luckily come across a random hero pick up. That seemed even less of a chance for me to ever play a hero. Earning battle points through game play works just fine for me... And probably the vast majority. Play the objective... Help your team win. You'll earn battle points rapidly. Unlock and build up your bounty hunter (and defender for heavy) star cards and you'll get there even quicker. I have rare (blue) bounty hunter & defender cards for my heavy. With both equipped and getting into some action (especially playing the objective), I get massive battle points pretty quickly!
