Between the two I would recommend LoTRO at the moment due to the balance issues and lack of information on future fixes from Mythic. They made many broad promises of great support and no major nerfs within Warhammer but lately that is not true. The latest free expansion (land of the dead) has virtually killed RvR on all the servers because the gear from that is better than most the RvR gear. Kinda stupid to introduce major pve content over a improving pvp content on a game that was supposed to be built around RvR. At the current rate of people leaving Warhammer the future of the game is really unclear. Many of my server Dark Crag are leaving for AION in September or going back to WoW. Personally I've been debating about getting AION but have gone back to wow in the meantime
