But even so Ranger, nothing is set in stone when it comes to banned blocks, until announced. So try not to start possible rumors. I know that wasn't your intention, but you even had me all like "We are banning slime blocks?" XD
S1CC: I don't see someone with 7 votes. Who are you referring to? Ranger: There are no plans on banning the slime block in Survival for 1.8. If any blocks are going to be banned (most likely the invisible barrier), an announcement will be made.
