Good you made this topic.
I agree with everything you say here except the 1v1 event which i really don't give a care about its unskilled and boring i prefer to see 8v8 and 2v2 tournaments.
Anyway back on topic. There been like 20-30 players that already suggested to remove isiloon servants or put them in the bowl forrests also the dark mares in eslant have the same drops as the colony zone ones there is even mages solo farming them and getting 30 monster stones in a single night.
Growmaster and VRHnegative should be spawned randomly in bowl like rainbow goblin. And make the mobs walking in bowl more usefull or spawn some death mares with exceptional weapons+1 drops something like that.
Eslant & Hell Abbys are a big meta and Colony Zone is a meme.
