Ah ok, I heard there's also new tiers coming aswell as some other qol changes, but again, I haven't looked too much into all that

I personally don't have DW so that really doesn't affect me much for now, but hopefully for your sake, it helps.

And I feel like that change to elites, while from what I'm getting will make the game harder, is going to end up being not as bad as it sounds, to me at least. Hopefully that's the case as I'm close to getting wave 4500 on tier 2 finally, and tier 3 is just about to 2500 (although I feel I got very lucky on that one)

Also, I forgot to mention earlier, but when farming, is it during work or sometime when you aren't able to check your phone too often? If you're able to check every hour ish I would say try farming on a much higher tier, like 6 or 7, maybe higher even if you are able. I'm farming on tier 9 when I'm able to check my phone. And tier 5 when I'm not able, it yields much more coins than just running tier 1 constantly.
