I just tried your faction and I think its very good. I tried it in GAE 0.2.10 and it works without any problems.
I'd like to post my constructive criticisms for your faction.
+ Excellent faction music loop.
+ Tree based buildings are great! especially the growing tree and the wood guard.
+ magol hedir looks good.
+ Tech tree is not too big or complex like some other faction mods
+ Unit models and textures are generally good.
/ 2d icons are well made but are hard to differentiate because they are all green.
/ Ents are not implemented yet
- The resource system doesn't seem to work very well.
- Faction is massively unbalanced atm. (this covers alot of different problems)
- Forge building seems unnecessary to house a single upgrade.
- Non-tree building textures need improvement.
- Griffon texture needs improvement.
Thats all I can think of right now.
