Guild Wars 2

now that you have dungeon rewards per account based, there is absolutely no logical reason to force players in repeating boring, unfulfilling and unrewarding content to unlock fun dungeons.

What happens if someone finds those events fun? I quite like the Arah and CoE chains.
Unrewarding? Erm, you get exp, silver and karma for completing them. If you simply got some porous bone it would still count as a reward.
So really, what you’re saying is, “There’s no reason to force players into repeating <subjective>, <subjective> and <subjective> content to unlock <subjective> dungeons!”
