I think /jump is a little op you could easily kill other peoples mobs e.g. sheep or pigs. So I think that /jump should be like overlord or highroller not donor.
I am Elite on mineverse, I also got /jump there. I have to agree, jump is really over-powered. Support tho!
About the mob/ animal killing part, I found this Claiming Land | Page 2 | Skyblock Forums No support on this. /jump is something really useful.
No support, I agree that having people kill your animals sucks, but /jump is basically the way to fly for donor 25 and stuff. Its basically one of their most useful tools. And also same for people who can fly since your friends like to trap you in boxes.
No Support. That would mean moving /fly up as well and as a person with both /fly and /jump I probably don't use /jump but maybe once a week.
No support. People will probably just end up using hacks instead. People donated and it would be horrible to remove the perk from them because of animal killing.
/jump is basically a faster way of getting somewhere, it's like saying remove /fly. If you don't want your mobs killed, lock your island.
