Yorick Ghouls in ARAM take too long to get 4 of

SO! Yorick is fun and all but how long it takes to truly use him to good use is to get him minions, now having a grave spawn every 12 minion deaths is pretty steep from what i can tell, and you can't really last hit when there are 4 other people auto attacking and using abilities to clear out the wave. Maybe buff him a bit for ARAM similarly to how Nasus and Thresh were buffed, otherwise he's great and fun just not very good when you can maybe get 4 ghouls in one setting, roughly 4-6 times in said game
