Since implementation of the new barter tiers and many more people bartering, i suggest raising the silver reward for the guild missions. As it is now its at 100m for 150 barters, and it makes it not even worth doing compared to say the x50 smh at 180m or 10k mobs for grinding mission at 200m. IMO it should be equal to the 50 SMH mob GM at 180m, this will make it actually worth doing and will bring much more life to the seas. 

Agreed.

All guild missions should be 180m-200m (just adjust what each skill needs to do PA), but I hope bartering GMs get looked at sooner than the others.
