I have leveled to 65 in no particular hurry, and I am almost done with the new quests in Mirkwood. Lots of solo content, lots of little stories, and I have toured the zone. “Now what?” as the players always ask.
The current end-game for The Lord of the Rings Online™ is three three-person dungeons, one six-person dungeon, and one twelve-person raid. The three-person dungeons have one, two, and three bosses, and the three-boss dungeon lets you summon them all at once for a big fight. The six-person dungeon has three boss fights plus a bonus boss if you complete hard mode. The raid again has three boss fights.
Not to seem ungrateful for the new content, but that is 13 fights to learn in the four-ish months until the next content patch. From that, we should subtract any bosses that are tank and spank plus adds and/or one special ability, and remember that you will learn most or all of a (non-raid) dungeon in one run. You will complete all the three-person dungeons on your first try with any reasonable group, although probably not the hard mode. The quests were lovely, but this is not a lot of Explorer content to keep us mentally occupied for months.
(I came to “four-ish months” by looking at the Mines of Moria™ updates. There were two big releases, then an expansion pack, in a year. I will not think of it as “more” if the same amount of content is released in smaller pieces with PR about how many content updates were released this year. On another popular game PR trend, calling normal updates “expansions” does not make them so either.)
It looks like the intended end-game is grinding legendary items. Again. Those five Dol Guldur dungeons give you talismans to exchange for LI upgrades. Run a dungeon two to eight times to upgrade one LI legacy one tier. Repeat about 20 times for each LI. Repeat whenever you switch LIs. Alternately, you can repeat skirmishes to get those scrolls.
Oh, and you need to upgrade your armor. Run the dungeons quite a few times to get those talismans your 25-radiance pieces or keep hitting the Book 8 raid until you have 120 radiance, then repeat the new raid to upgrade to 180 radiance once you have its hard mode on farm status.
Back to your legendary items, you already know that you will need to replace them. You probably will not spend your LI upgrades on a 3rd Age weapon, because you will eventually craft a 2nd Age that you like, but there are no level 65 1st Age items yet. Those will arrive someday. Do you want to save up and muddle through, or have the best now knowing it will be trash in a few months?
We are all enjoying the first month of the new expansion. I am wondering how big the backlash is going to be a month from now when even the most casual players have been able to hit the level cap.
On the “trash in a few months” point, it has become a ritual to announce when you destroy your previous main weapon. Variations on the ritual include mentioning how many months you had it, how many hundred LIs you went through to get it, or how much gold you spent for it on the auction house.
