Any word why they removed multiple leaders in Draft and when we’re getting them back?

In no particular order, they've removed Mobilization (NR), Inspired Zeal (NR), Arachas (I think it's removed, MO), Call of Harmony (also think it's removed), Hidden Cache (SY), Tactical Decision (NG), there are definitely more but these are off the top of my head. Particularly, Hidden Cache and Mobilization were interesting and Mobilization allowed for multiple pikemen/crossbowmen which allowed different-than-usual strategies which no longer exist. Also, any word on them fixing the disparity of Core cards where Ball = Kaer Saren for whatever reason? There are also other notable cards missing such as Kelly which used to be in the pool but were removed. There are tons more missing cards which would be nice to have in the game such as Brute and Vernossiel and if you've played Draft w/ Bounty, you quickly figure out it sucks without having big boys. Also there are outperforming leaders such as Blood Scent (not the leader itself, it just allows super powerful Vampire packages) and White Frost (same deal). There is also Shieldwall but that has always been strong and it's not as oppressive as the other two when they are played at optimal level. I know it's out of beta with the only change being that we now have rewards and entry fee (obviously that was stopping the mode from being 'released' for nearly a year) but it would be nice if this mode was given any attention and we don't get 1 patch every 6 months. I know it's not a priority as balancing Standard and its 6 unit changes a month which is about 1 a week for a guy at a rate of 1 change for 30 hours of work for changing the power of a unit by 1 but it would be nice if this guy also balanced Draft from time to time.
