Why do people avoid getting better at the game?

[MistakeNot]

Jokes on you, the dungeons get significantly easier over time. They practically play themselves.

No. No, they don't get easier. On the contrary the later dungeons in the game are significantly harder than the early ones.

Nowadays there is really only one mechanic in the dungeons, and that is to avoid AOEs. In the later dungeons you have much less time to react to AOEs, and often less safe space to find.
In some cases the time to react becomes so short that unless you have already memorized where to stand there is sometimes practically no chance to avoid an AOE.
This is not the case in the early dungeons - there you usually have a chance to avoid the AOE attacks no matter where you stand when the boss starts casting.
