Man, I remember when Aatrox was in the LCS. Those were Darkin days indeed.
I remember when he was disabled because of the two-hit->heal thing.
Mains are safe
Heimer has been used a total of 8 times in Pro-Play. Camille has been used 190 times. Elise has been used over 1000 times. Within the last 12 months.
Also, all the times Heimer was played were in 2013 or earlier. So the odds of him showing up again are... 0.0000000000042%
