I have started work on rewriting the expansion rules. Not as bad as the originals, still needs some help though. I should have the base game FAQ compression done sometime soon.
Galadriel has a very odd set of rules stating that she does not count as a companion for events, she only counts as a companion for Combat Cards. This particularly baroque set of rules currently has the sum total effect of not allowing her to get "the Eagles", that's it. Just maybe there will be more cards that she may not be able to use, but right now it does seem a spectacular over reaction.
Why not just have "Galadriel counts as a companion, except she cannot summon eagles". Technically she cant use through a day and a night either, but she cant leave Lorien so that is irrelevent too.
