I hit Prestige 45 a couple of weeks ago and my best option was Betts, who I sold for $22K at the time. Disappointing, to say the least...
Anyone who hits Prestige 45 almost certainly has the live series completed. Instead of the Live Series Lottery, it should just be a flat amount of Stubs like $100K or something (the $10K rewards along the Prestige path are pretty silly, also).
