We know there's at least one quest in Ered Luin that's listed as level 5 or so while all other quests around it are level 6 and 7 and 8. Not all content is flagged correctly. If a player enters the region at 7 and follows the general path, that one quest will end up green while all others are dark and light blue.
In general, those are not bad things in LOTRO Gold, because it means that one isn't gated from advancing by any particular quest or deed. If they don't like the soul-crushing bleakness of the Lonelands, they can opt for the North Downs. If they can't find a group for GA or Pulling Beards, they can skip it.
If they really don't want to go grind out 240 worms, they don't have to. Can you imagine if it were structured so that you had to kill all those worms in Ram Duath, or crawlers and trolls in Trollshaws, just to get high enough to do the next region?
The issue is that while there's real choice to the exclusion of content, there isn't real choice to its inclusion. While people should be able to opt out of grinding these worms or those lurkers, they aren't able to opt in without making content trivial around them.
If they WANT to do everything, they can, but they aren't able to do it all at its intended level. And that lack of ability is what needs to be addressed. If you want to make your character stronger you can buy LOTRO Gold service from our site.
