What would you like to seein patches?
Though I have only had a few hours with FE:LH so far, I have to say I love a lot of the improvements, principle of which is the skill tree system. However the one thing I would like to see is larger maps. During FE I played only a few games, but were they games. There was a mod that expanded the random map sizes enormously and I enjoyed the large games far more than the smaller ones I have now. I don't know if anyone else feels this way, but for me the really get a feel for the world of elemental the map needs to be huge and teeming with wild lands and monsters that you have to bash your way through before the kingdoms can even meet and go to war (save those instances when you were spawned close. So for me I would like to see stupidly large random maps in a patch or even DLC.
