A lot of the reason why these suggestions about fixing PVP are met with skepticism is MM's many times stated mentality of "it doesn't do that on vanilla settings"... it's disheartening because he comes off as if the current game is good enough, and any problems you have with the current setup aren't important if you're changing options, much less modding.
I mean, do y'all even realize the lcb doesn't work properly? And that's not even a mod!
That mentality has been extended to PvP quite a large number of times, too. "This is meant to be an 8 player co-op game", blah blah blah.
When take something as simple as say, "if you have too many recipes, because all recipes load in all workstations you'll get serious lag" and he responds with "oh well, play vanilla", he's NOT saying "we're in alpha right now and we'll work on that later", he's saying "suck it up, we aren't worried about the future."
So I'm /hopeful/ that these things will eventually be addressed, but MM's method of communicating make people think otherwise.
/hoping he explained the skepticism well enough
