Lets start from the begginig (seriously?):
1- Nowadays you get coalitions depending in your products, not in your strategy, because they are so expensive and hard to take enough tea/wood/whatever for only 1 coalition, and dont talk about taking 2 or 3.
2- Another nation would be great, it'd be something new that can make the broth to taste different, and maybe it could be a way to stop with the archer and arty spam. Its a strategy game and thats the safest one but Nexon doesnt help it.
3- Thats a good idea too, but at the end generals are just a strong cavalry, they dont have nothing special than a good bunch of damage and health. The best thing Nexon could do is adding perks or special abilities to generals, different in every of them. That rock!
4- I dont understand it too much, but I think you mean to remove the glory sistem. Well, we need glory by the same way we need trophies to go up in the ranking, so... Nope.
5- I dont use to be pesimistic, but I think its right, non of these things will happen at least in the next patch, hopefully they put something new but atm we just can sit and wait.
