So when I play against the AI, I love the green dragon, I almost always buy him as I fly around and ruin hunt. I've gotten my paladin hero up to 28 or so moves with the boots & walk stuff.
So its a really fun unit. However, I have rarely ever seen this unit played in any games. If I ever see it I pillage it. So I think it needs to be tinkered with. Here's my theory: Let's color it black and call it the "dark dragon" or "black dragon" and give it some fear, because you know, dragons are scary and all .
So all I say you do is change group move to +3 instead of +4, add a -3 fear, and move HP back to 2 from 3.
I think this would be a cool unit with just a little more value and a nice touch of fear to go along with the moves. I think it would get some play.
Now all that to say that if you specifically named the dragon the green dragon in homage to Lord of the Rings (http://lotr.wikia.com/wiki/The_Green_Dragon_Inn) then I guess maybe dont change the name
ok just a thought....
