Gems - The main issue from my viewpoint is the over/under on the ability to maintain and complete collections. A reduction of 16% for these tasks and then also taking gems and converting them to gem keys at gem keys full purchase price value - which I guarantee nobody getting legendary tasks uses, is a far bigger hit than stated. Even if you can’t hand out gems here, the general perception is that these tasks have taken more than a 16% hit for free-to-play players, and a gigantic hit for VIP 5 players. The concern is that they will no longer be able get mythics with roughly the same reliability for roughly the same amount of effort as pre-patch, which mitigates the usefulness of crafting - if you were already getting the monthly mythic and now miss one, but have to wait to craft it, crafting as a whole is a net loss for you. Since thing crafting was supposed to address was the ability to complete collections, this seems a bit backward (unless mythics are going to stop or be slowed down on the release schedule in the near future, in which case I stand corrected but would also be somewhat disappointed). Others might not feel the same way, but I personally have no problem buying back in once I have calculated at least a zero-sum in my collection rate after being able to shift some of that toward getting stuff I missed previously as this was what I wanted.
AI Issues - There is a perception that cascades are bigger on Unity. I would assert that they are spikier. New mana rules make cascades feel bigger as well, and this can’t be ignored (match 4 surges, new blob match rules). Mana gain in general felt much more balanced on Adobe than Unity.
Dungeons and Diamonds - Pure good news, thank you.
Summoning Stones - This will be interesting to see. However, again, 8 troops per week is far too long to get through the catalog to be able to get to the one you actually want (unless it is 8 troops per rarity per color). A fixed 4 to 6 week rotation of every troop in the game of any given rarity tier seems to be a good target here, you should not be waiting potentially 3 months or more like how legendaries are now. Additionally, common/rare crafting out of much fewer resources maybe? At this point, it would be just to get copies to get ascensions with. Gold keys will get you there, but you have to flip enough gold keys to mythic every troop of that rarity tier in the game every time a new one is released, and while like quantities are available at endgame, this is often a chore because it involves opening 20-25k gold keys in one sitting.
Crafting Mythics/Legendaries -
No objections to increasing the count available at any given time here (see above). I felt that the cost of the legendary craft was a bit too high relative to the mythic’s cost while sharing a bottleneck resource.
