I have 12 workshops, don't cycle quests, and have sufficient supplies for my city's purposes. So far the devs' response to players' not wanting to rely on the looping quests (build a magic academy) are completely unappealing to me.
Aggressive ranking hunter me really, really, REALLY is uncomfortable with the idea of building a building that can't be deleted, uses an extremely limited quantity item to produce things, and does nothing for your ranking if you run out of the limited quantity item. The devs' recent changes to the battle system which make winning provinces impossible if you're too far out on the world map just make me more uncomfortable. So if it isn't x relic tournament week and I need x relic to make y spell I am sunk because I can't win that relic from provinces because the devs think I've gone too far? To me, that possibility is absolutely terrifying, and is the big reason why I'm never going to build the magic academy. So that solution is very unsettling.
The solution of magic workshops also makes me uncomfortable. Part of the challenge of this game is balancing supplies with population and space, and having to decide between premium buildings which give extra population and take less space but don't give coins and residences which take up more space but give coins. Magic workshops and residences, combined with the wood elf premium culture buildings.... I dunno, it just seems like Inno is removing all challenge from it. There is no downside to buying all premium buildings to get your population, culture, and supplies in wood elves. Doing that, while simultaneously saying the people who are pushing out farther on the world map and who are building more manufactories than the devs want are bypassing the challenge the devs want is.... hypocritical, to me. If the devs want all players to solve puzzles, they shouldn't make it so that premium players have no puzzles.
Increasing the supplies per workshop would be the best solution to this problem. Increasing space allowed so players can simply build more workshops is also a solution if devs don't want to change how many supplies the workshops give.
I would be happy if the repeating questline was replaced with a similar repeating questline that takes longer to complete than the current one, and offers goods and broken shards as rewards. Or items to upgrade event buildings to your current chapter. Or even which awards relics, since the devs seem so determined to cut our regular supplies of relics while giving us so many things we need to spend them on.
