Maybe I should check out either Brandywine or Landy. Sounds like it's more fun than Ridder atm.
Well, good luck with them, both! I hope you will find what you're looking for in those 2 servers, as far as PvP's concerned.
While more and more new players decide to try firstly Gladden because of the forums' statistics, it's a common secret; the majority of the "hardcore" PvPers from every US server
take the risk and join Brandywine.
Personally, I support the new entries there, because I have seen them improving themselves quite fast. Moreover, I have faith to the new high ranked transfers there, because
most of them are very experienced in PvP stuff. Their will to try might help LOTRO PvMP itself!
As for Landrover server, idk; all I know is that quite few players from there have already xferred to Brandywine. Correct me, if I am wrong.
That being said, if you really want to have some very cool GvG/RvR fights against some very good and respectable foes, then Brandywine is what you're looking for! No doubt it!
In other words, Brandywine is your " A m e r i c a n D r e a m ", if I may say so!
