Regarding the tediousness and boredom potential mid to late game: I've experienced some of that, but I think a big part of that has to do with animation speeds. At this point in the campaign, we've learned the mechanics and generally what is happening... but to watch 2-3+ archers fire 2-3 shots each with that unforgivably slow animation really starts to take its toll.
But if the game would be balanced in the mid to late game such fights would be still challenging and i think that this is the reason why some people are complaining about the game balance.
