Some Suggestions.

Some things i'd find useful. 

Spec refill - In a donator area. Although this could increase rushing, I wouldn't expect it to since donators normally follow the rules. :p

More variety of potions. Such as super-anti potions which would help me in PvM. ;o

An ::empty command. 

Some sort of PK table which shows Kills/deaths or Kill streaks. Or add something like once you get a kill, you get 5 points which go up on the table for others to see and even compete with.  But make it so the table get reset after like every update, or after a certain amount of time.

Also i've noticed some annoying thing where when you click a potion it takes a little while to eat your food, this had been the cause of many deaths in pvp.

Make slayer a skill? I know we just type ::master but it'd be nice to kill some NPC's other than bosses and get some different type of loot? ^^ Also add some sort of slayer shop and you can buy the items by gaining points from finishing tasks.

Good suggestions C A P S, hopefully Blaze will consider these.

like the ::empty one =D
