I am very impressed on how much effort the team put into making The Hobbits. I mean, this is exactly the way I would have imagined them. Unicorns are a great addition, because who wouldn't want to have Unicorns on their favorite Faction? I would request that Unicorns can mounted by Hobbit heroes, and fly the into the enemy base with style
I would also like to request that Gollum become a playable hero, and him to be exactly like he was in the Battle for Middle Earth 1. This is because Gollum was originally a Hobbit, and would obviously join them if the Hobbits just felt like going to war. He can also ride Unicorns too, obviously.
Maybe I missed something, but it seems like the Hobbits don't have many unit upgrades. Well luckily I'm here to give you some suggestions. Well as we see in the films, rocks thrown by Hobbit can kill anything. Goblins, Orcs, Heavily Armoured Uruk-hai. And they also have excellent aim, such as Merry and Pippin somehow getting Rocks while on top of Treebeard(who should be usable as a summon) and sniping orcs with them. So I would suggest that the Hobbits get multiple rock upgrades. They should be able to throw Fire Stones, Silverthorne Stones, Steel Stones, Forged Stones, Master Stones, Meteor Stones, Catapult Stones, Trebuchet that Gothmog barely dodges Stones, Cannon Ball Stones, Balrog Stones (which is actually a thing in The Lord of the Rings Conquest), Shiny Stones, Grond, Bombadillo Stones, and finally, Haldir Virtual Soccer Pro Soccer Ball Stones Sponsored by GameStop (Credit to Ruuddevil for this idea). They can available at the Citadel and cost 100 each, and you should be able to give your hobbits every upgrade at the same time.
My last suggestion is to make Ale an be upgrade for Pippin. We all know that Pippin likes to drink Ale, especially in Pints, and once upgraded with them, Pippin will run in random directions and use abilities when he feels like it. But he won't be allowed to ride Unicorns, becuase Drunk Driving is illegal in some places or Middle Earth. And we don't want to put the lives of Orc Labourers everywhere at risk.
All in all, I think the Hobbits will be a great addition to this Mod, and Hope the team continues giving us amazing faction such as this one.
