If I had to remove one thing from minecraft, I'd probably remove cows and dairy, because it cheeses me off. The cup's half empty, not half full, when it comes to milk buckets. It's no use crying over spilt milk, so there's no reason to have a cow when I mention removing cows and dairy. You can be stubborn as an ox about this suggestion, but don't be such a bull. Cows are too big for their britches, because the grass is always greener on the other side of the fence. And if you don't like my idea then don't fawn all over it please. I might have made a moostake by suggesting this in the midst of a crowd of bovine beneficiaries.
Woah, and my friends think I make bad puns...
Well, I can never come up with 1 answer, so I guess I'll start with 1.4+ Skeleton AI. They're a royal pain in the neck to kill. Also these things see me through walls and that isn't cool man.
Then there's most of the fanbase of the "Team Crafted" stuff. When I say most it's because not all of them are bad, others are just "meh, hes okay i guess" and I dont hate them for that. To be honest Sky a.k.a Adam and Bajancanadian were way better when they 1st started.
I wouldn't touch any mob removals really, and despite most others I'd rather keep the bat and silverfish!
That, and in a sarcastic sense I'd remove lag. But hey, who wouldn't?
