Seriously? Crashing is your system, lag is your connection. Other than the culling, which they’ve already discussed their plans for that, you’re complaining about things that they have no control over. Not their fault your system can’t handle the game. Sure, there are some issues. Every game, MMO, PC, console, board games even…all of them have some issues of one kind or another. Client crashes, overflow, and lag are not the company’s fault. Change your settings or upgrade your system for the crashes. Get a new ISP or better connection plan from them. Overflow happens, be thankful enough people play the game to cause it, it’s a good problem to have.
