The mighty voice of reason (Epicsause) has requested that I stop arguing with the PvP community. Can an admin lock this thread? It no longer has a purpose.
I would love for ender pearls to be replaced with something that doesn't negate creative building entirely. In 1.8 slime blocks will be added which will make it possible to build seige towers and moving airships. I think it would make PVP a lot more interesting if you had to actually be inventive to get over walls.
