I have a few ideas that everyone might not agree with..
1) Back in Deathzot 8.0 it was way harder to get your mining and your T1's from crafting, It should have a smaller rate to getting them like a 10-15%
2) If lowered or thought about a little you should make 10 Ruinic Starstones turn into a Greater Ruinic Starstone, This would give a slightly better chance but nothing like 45+% because then its almost guaranteeing a free item.
3) It seems that fishing is becoming the way to mass produce money and level from botting the fishing spots, and higher levels luring into town.. You should make a island ment for fishing and make it non-fishable around the city do to the big mass killings that the "tutors" like to have.
4) Some monsters should have health lowered slightly do to character levels and slightly different HP Ranges.
5) You said you wanted the event rooms to be fixed, and by that not have botters waiting afk there for the monsters to spawn, so every event you have 5 minute warning, You get in.. Once the boss spawns the teleport dissapears and no one can get in, When the event is not going on the teleport is gone, or closed meaning no one can get in or out until the event is on or over with.
6) A couple very active GM's that can stand by and help, You just made some characters "tutors" and they cannot talk in red or even really do any tutor powers. Even though there isnt much to a tutor.
7) Candy Canes should work for all levels, I mean it only gives 1 level so higher levels can use them still to get somewhere.
