I'm a bit careless on this becoz I placed the mountain right at the middleplace when the defender got a larger deployment area. However, after checking the map by playing against the cpu, I found that the attackers can reach 5/7 (20/28) height of the mountain and the defender can reach 3/4 (21/28) but also with the trees. I suppose the defender now gets some advantage, however, I hope you can check the map out to see what the actual situation is.
Thanks for your comment and I'll be careful on that next time.
