Hello everyone i never played Lotro to max level, so having a free account brings up alot of questions.

If i get subbed in order to play Legendary servers , will i need to buy a new expansion after every patch?
Are questpacks still included in the Sub?
How slow is Treebeard server? 40% of xp seem like alot of grind but i do like 6 months between patches, 2 months is too fast.
Do u need to fellowship xp grind on treebeard?
Do i need to pay to unlock classes that werent in original Lotro?
Thank you for reading
