I believe your wrong at some point there... The tradeshop glitch had to do with already having your items in inventory, and that is the only reported problem. As for the lag problem no issue skyblock ran the same amount of people 2014 and hoppers did fine. The real reason is they don't want any duping at all. This would ruin the server and a lot of people would quit if a reset happened.
Grown? There's less people than there used to be. Server ran fine when they were enabled from what I remember. Also just an update I think this is just built into most servers now. It's on literally every server I've played with hoppers.
Hoppers aren't going to be enabled for a long time. I don't trust hoppers and never will even if we patch it, someone will eventually find a dupe.
So some people says that 1.9 is coming tomorrow. Do you have any idea when the servers gonna be in 1.9?
It doesn't matter when 1.9 comes out... All of the plugins need to be updated to 1.9 features. It's going to be a long time.
Thing is, most server have patched hoppers. Dont see a reason to not enable it :/ Regardless, thank you for at least responding to this thread, it does make the community understand more of the situation
