Personally, I quit Hearthstone prior to the release of the Scholomance expansion. The main reason I quit Hearthstone was because RNG became too big a factor, and I did not enjoy the player experience anymore.
However, the reason I won't come back to the game is: the economy and packs. I have thrown more money into Hearhstone than I'd like to admit, and even so my collection is far from full.
- It is simply too expensive to catch up. Hearthstone offers little to no help to catch up. There are only two ways to come back: 1) Pay up 2) A major grind. I do not have the patience to grind Hearthstone because the I don't like the player experience enough, so that basically excludes option 2.
- Packs! Because even if I do plan on spending money on the game again then the pack system might screw me over. I have bought multiple pre-order deals and 40 pack bundles (50 €!) and often I have not gotten anything out of it. Sure, a bad legendary, a bunch of useless epics and so on. But the cards I need? Nah, better luck next time. It's just tedious to open packs.
Compare this to Legends of Runeterra: Great economy, F2P friendly, you buy cards and not packs and so on. I have been able to craft the entire previous expansion (except for a few epics), and I can craft every relevant card of the upcoming expansion. As long as Hearthstone is more of a gamble than a collector’s game, I am out - except for a few game of battegrounds here and there.

Gee, I can only imagine what a Heavy Bestowment would look like.
Next, create a minion that supports a Zoo Priest archetype.

When I first got into playing, I dusted Leeroy Jenkins and Edwin VanCleef to craft Yogg-Saron.
