T1 alphas are very scarce

I'm a cavalier player and i have a lot of rank up/level up resources that are about to expire in my stash because the only thing I'm missing is t1a like seriously 5 star champions need sooo much t1a to rank up when there are very few t1a out there to get. I already spend all my glory on t1a every week, get 5 t1a from master and heroic difficulty EQ and grind the t1a arena and i still can't have enough t1a to rank up my champions this is ridiculous. Please do something about it kabam, either cut down on the amount of t1a needed to rank up 5 stars or make t1a more available for cav/TB players. I suggest having a crystal that has a high chance of getting t1a or a quest that can reliably give us a lot of t1a.
