So this has probably been floating around for a while now, but here goes. Everyone here is probably familiar with 1.9 and what it did in some way, one of which is the attack range debuff. Because Mineplex is compatible with 1.8.X versions of Minecraft, that means that people can play in 1.8 versions and get a significant increase in attack range. While this affects a couple of games, the most problematic issue it causes, is, well, gladiators. 1.8 players get a huge advantage and can attack opponents from way further than they can, which also pushes them back, causing them to win just about every match with little to no effort. Since there's no way for Mineplex to change the coding of Minecraft itself, I think the best solution is to just have 1.8 players sit out of gladiator games. it's either that or just outright ban 1.8 players from nano games in general (which I think is a little extreme). This is also a small problem in reverse tag, but it's slightly less of an issue there.
