World of Warcraft Gold which we use in the game is very useful, and we need make full use of it. But now I think you can have a try to make sure it.
No one can does everything right still, and there are many people helping you. We also buy rupees to carry out this game, and we can change it for us love, if we have a chance.
Now some guides to party are there, you can follow it if you are interesting in it.
Buffing - It is really the easiest part. First of: after initial full pt buff, try to divide your pt on two. I would not recommend 3 groups for buffs, coz you will end up drained every 10 mins and you will struggle between healing and rebuffing some of your pt members.
Buff yourself too! Int, vit, shining armor at least, at some point you may become overweight so if you need to Buy Lotro Gold move around give yourself and STR.
Mages - learn this: they need full buffs, all available, no exception! Hunas might not use their cc skills, but if it happens that they have to it is better they are able to land teir spells.
Pets - do not be cheep buff them! If it is a pixi add int. and yes they all need str no matter if it is a pixi or not. Blue pixi are p.atk based, yes they support healing but if no str, they hang in there and will be useless. Red pixies ? after they unleashes their power, their normal attack is also str. based.
If you have Cheap Lotro Gold, you can continue it well.
