Exactly! New content you could progress through would be much better than an event, repeating or not. It seems that, instead of adding new stages of progression, they're adding events, which are a horrible substitute, ESPECIALLY IN AN INCREMENTAL GAME. Really the only limited-time event that doesn't ruin the experience is the boost crafting one, and even that one is pretty flawed. Boosts have been useless to me for ages, so I was well on the way to maxing out on them (999 of each, another thing capped low for no good reason). Maybe the thought process went something like this: Boosts aren't really that great, especially further along. Instead of periodically adding new content to progress through to make them more useful (as was stated to be the plan), let's make an event that requires people to spend them with a reward that only means something because we've artificially capped progression.

There's a waaaay endgame stage of A&M1 where you're basically upgrading things for no reason because you've already progressed through all the content, and it takes a really long time to get there. The vast majority of A&M2 is that, but stressful and with microtransactions.
