Why not remove the mission? Replace it with new system on how to get points. Like for example 1 kill = 1 point. It's also funny to see that 1 player can win vs 5-8 members of the other guild just by kiting and doing missions(not a fan of this tactic). Emporia is a guild war so the present members who are partificipating in emporia should be a huge factor in game. So if you don't have enough members in guild war you will have a hard time winning against the team with enough members. Honestly, it's my friend that won against a decent guild in emporia and he's using an archer.
