I like the new league mechanic too, it just needs a little tweaking.
It is all the bugs, Syndicate intervention FPS drops and getting one shot, maps rarely spawning (it is FAR worse than it used to be, everyone is complaining for a reason) that really need working on. Having a simpler league and some breathing room to iron out all the issues would be for the best, I think.
I don't have as much of a problem with the "too much content" issue as some do. Just pick and choose what you want to focus on. However, there are a few things that could be improved in that regard too, because of how compelled everyone feels to run delves/memories/incursions etc when they hit their sulphite/node/temple caps.
I really don't think the issues are too extreme, but I'm not going to run white tier maps at level 86 and burn through alchs on t3 maps. Thats a fucking joke.
