The Lord of the Rings Online forums have spilled the beans on what will be getting fixed with the game's imminent update. The downtime will occur on December 6th, from 6:00AM (ET), and is expected to last until 12PM. This patch does not really contain any new content, however, one of the fixes will open up another option for PvMP players -- or rather, re-open.
The update should bring back the option to choose Trolls and Rangers in session play, which we reported on a few weeks ago when they were disabled. At the time, they did not say how long it would be before they were reintroduced, so it's good to see this feature back in the game before Book 12 is out. The question is, will there have been other tweaks to how they play, to address the balance issues many have been complaining about? Or, looking at this thread -- do people even want them back? The scale seems to tip heavily towards 'no', with the topic-creator keeping a tally: 12 for them, and 25 against.
Other notable fixes for this update include some DirectX 10 performance improvements with shadowing. Full pre-patch notes can be found after the break.
