They won't. I understand it's frustrating and sometimes it helps to vent, but what you see is what you get from this game. There will never be a fix for sandbagging, a rebalance of nations, a fix/ban on obvious cheaters or anything of the sort. Those take time and effort that BHG/Nexon is not willing to invest in this game any longer. Plus, the people at the very top who have already maxed everything in less than a week like things just the way they are. Maybe we'll get alliance leagues and new AXP levels at some point though.
The game can continue indefinitely as long there are people still playing/spending. It's up to each of us to figure if/when the bad outweighs the good. Just saying when Tin Soldier likes every post that basically says ''shut up and quit complaining'' it seems to provide a window into the devs' mindset.
