Honestly, the reason noone played anymore really has nothing to do with balance; this game was WAY more fucked up 3 or 4 years ago, and i've been playing since 2011 so... lets get down to it.
Strat is an abysmal asshole that seems to be shitting on everyone. its not fun anymore, at all. Its really unbalanced and expensive, and its just balls overall. we need a reset, and a rebalance; shit needs to cost alot less and there needs to be less penalizing mechanics.
Maps are getting too big; when you make these maps where you spend half the time looking for the other team like some benny hill episode, its too much. even the duel map is pretty lame. the old arena was JUST FINE, and the new arena is good, but whats with the ruins? also the fog sucks, especially that mars landing fog on sand maps.
Smaller maps, more fun, less obstacles, we dont want to play golf, we just want to play a battle map with a place for two groups to meet in the middle and kill each other.
Finally, just realize that this game is old. mount and blade has been around since 2005, (i bought into the .5X beta so i know), and people are going to move on. I realize warband is 6 years old, and crpg is like 4 years, but it gets old after awhile.
what i suggest is that the community begins to look into why new people aren't joining, and make sure that people aren't being turned off from it if they are and then leaving for something else. Honestly, i can't see why they would.
The ultimate agenda here too is for chadz and his team to make a game and make money, so they are focused on that right now; I have no problem with that at all, and as a matter of fact i look foward to melee: battlegrounds. keep that all in mind when we start pointing fingers at these great people for trying to make a living rather than tinkering on the game everytime someones incontinence exceeds their hubris, and people need to just shit all over the game to fit their own end.
