First Step
I just wanted to take some time to suggest the removal of Redstone from the PVP mine, from my experience as an avid PVP-er I have seen both sides of the bugs that have occurred in PVP mostly due to Redstone ore blocks. Redstone as a resource is extremely abundant and taking it out from the PVP arena would be harmless, as you can get it in most mines on the server. In terms of the issues it causes, the gapple glitch, which is a term that is thrown around a lot, but I have found that if you try to eat a gapple whilst standing on a Redstone, it glitches out and doesn't allow you to eat. I'm sure you can imagine this is extremely frustrating. Also, potions, if you are trying to drop a splash potion while pvping, good luck because since there is so much restone everywhere if you by chance throw a potion on a Redstone the effects won't work, or the potion just will not throw. Lastly, the wither and Redstone combo, this one is the worst, if you get the withering effect from a sword or axe and are currently on a restone ore, it acts like quicksand and glitches you into the block, you cannot move, you cannot jump, mine, eat, or anything until you die, or unitl people stop hitting you and your withering effect wears off. Please take some time to look into this issue, and hopefully, the removal of restone from the pvp mine is the end result here, this would mitigate a ton of other issues on top of the ones I mentioned above.
