For some reason, LOTRO hates solo players. If you aren't into group playing then stay home 'cause you'll be frustrated.
After being away for about 6 months I came back to LOTRO for Mines of Moria to continue the fun. All I can say is that if you aren't in a group then don't even bother playing. Maybe it's because I'm playing a hunter, but maybe not. Either way, it's far too frustrating.
Why? First, the adds are impossible. Attack one guy and 3 more come out of the woodwork. Literally since sometimes they walk through walls. The threat area is far too big. I can be far away from someone and all of a sudden they come running after me. With the way monsters are spaced out, it's next to impossible to get through an area without having to fight your way through. However, the respawn rate is pretty quick so if you go too slow you'll get stuck with guys on all sides. Of course if you go to quickly then you'll pull to many enemies and be dead.
Another thing that makes me want to scream is getting dazed. Almost every single time in combat my character ends up being dazed just when they are getting to the end of a long spell/action. Once in a while is fine, 9 out of 10 times in combat? Come on. How come the enemies don't get dazed left and right?
Another annoying thing is trying to attack when there are several mobs on you. You can never get a shot off. They keep hitting you and stopping you from attacking, but when you hit a monster that is attacking or casting a spell it never stops them or delays their action. So, again, if you draw more than one enemy forget it.
Then there is money. One thousand silver pieces for a piece of gold? Then you get 25 silver for a quest completion? It's like "Hey, can you risk your life and save my butt by facing several deadly creatures and killing them for me? I'll give you taxi fare!".
The mines themselves are great and and the new weapons system is fun. However, if you can't do any quests solo because you get your butt kicked then the fun kind of goes out of it.
Sure, I could play with groups, and I try to. However the attitudes of people online have been getting worse and worse. No one helps anyone any more and most people seem to want to play just to show off how much they have or how good they are while knocking everyone else out. Not exactly worth paying for. I'm sure there are still good people out there, but it seems that when people hit cap in a computer game they somehow think that they are better than everyone and I like to avoid these people as much as I can. That means soloing. Since you can't do that in Mines of Moria it's back to WoW for me. Yes, there are even worse rude people in WoW, but at least I can solo and have fun without getting screwed by the AI. Seems like WoW is there for you to have fun. Not sure what LOTRO has against solo players, but it's definitely not fun for them.
