Unlocking other characters...

I was wondering can you still buy characters using experience or is it only GC now? I played the trial a while back, but I forgot :c I'm about to buy the game so I'm wondering if I should buy the GC bundle too

You can no longer buy characters with xp (wouldve taken 2 years anyways)
You can now buy with gc still AND ingame dollars (still overpriced as fuck)
basically only buy with gc
