What's your first impression of Eureka?

That's a really terrible thing to say about hands hurting. Like, genuinely terrible.

All I'm saying is that if your hands hurt here, your Hands must hurt in pretty much every other content, because the amount of buttons you spam per minute is the same.

The rest of your post just blatantly overlooks the difference between this content (sitting in one spot doing literally the same thing over and over with no downtime or breaks at all) which only really has Diadem 1.0 as a 1:1 comparison to (which not coincidentally had people complaining about the same issue).

Then just take a break.
Am I missing something? You can just pause for 1-2 min after every 30-chain pull for example, so what?
Do people really say that A1s/A9s farm was waaaay better because you had a loading screen now and then which "allowed you to pause a bit"? Lol.

Because of this?

If there's a pause your group is trash.

So, that's true for all the other contents, too.
A1s at all? Your group is trash, bc srsly A9s was way more efficient. A1s with more than 2 heal/tanks combined? Super-trash.
A9s was: Burn faust, when he's about to die move already towards boss, ignore all adds and burn boss before faust add spawns, ignore chests and leave asap, reque asap (no "I need to repair/trade in tokens/tomestones" pls).
If not "your group was trash".

This content is waaaaaaay more "take a short break" friendly than any other grind content. Because it's no problem to say "brb, 2 min" while the other 7 just continue with killing mobs, compared to holding back the whole group because you need to go to the bathroom quick.
