I can only speak to my own experience (thought I presume it would also be the experience for many others), that the update most definitely encourages me to gem more often.
I already used to be a mass gemmer (clan donator/wars), but that was my choice. I chose to do that and "invest" for clan quality of life. I felt good about it.
Post update, to stay ahead, I've been boosting every session and storage raiding. While the bases are pretty garbage, I can still profit with high activity and boosts. I've also been pushed to gem my queen to make storage raids easier and to be able to participate in wars. This pressure did not exist before.
Not only that, boost times were WASTED as a result of both PBT malfunctions and normal functioning. Without indication or self-timing of cumulative play, boosts often get interrupted by the triple kick.
I've also been forced to purchase VG, which I will now also relate to as "10 Gems to save CC troops" because of a kick message right before a war attack.
All of these things make me feel more pressured to buy gems and it doesn't feel good at all. I did not feel pressured in this way before.
Therefore, my current $100 google play balance WILL be withheld from this game as I do not want to fall prey to these kind of game design tactics (greed).
War without heros was already a problem, but I feel like I need my heros to farm and defend more than ever. I was excited to spend this money on the game to continue with donations, hero upgrades, and boosts, but I grow with hesitancy each day without SC announcement, shakiness of economy, community uproar, and staleness of gameplay.
