I would say about 5 for skill but 6 for entertainment. Really entertaining game with lots of big battles. However there was some sloppy micro ie losing horses to trolls and a few things like that.
Losing horses to trolls? That would be hard seeing as it was a double fol mirror, but yeah I agree with your scores. Rohan shouldn't have gone for RA and ents, Gondor should've got TGs and had better Gandy/Knight micro.
There are some really good battles here and I think (imo) you will enjoy the watch.
