Heres a few things.
1) Theres too few spawns, everyone hunts at the same spawns, since theres better creatures, and worse creatures to hunt, lets take mad mages for example, they are fast, have 100k HP, deal shittons of damage and practically always come in groups, which makes them horrible to hunt, oh and theey keep theyr distance so its even worse for knights, and mages too since theyr staffs cant reach em. Fix up the creatures abit, add more creatures and spawns since u gotta hunt the same creature for ~3k levels sometimes since theres no good alternatives to it, even tho it gets easy for u.
2) Paladins - Yes, yes, i know people hate it when theyr class gets nerfed but paladins are atm way too strong. They are tanky, deal shittons of damage without even using spells (T2 Weapon with 150 Attack that can shoot at all distances lmao) and they even have the practically best AOE spell in the game (5k damage AOE on lvl 600 that has no exhaust). Take a look at them, and keep reading to number 3, u dont really have to nerf paladins all too much, rather make em a strong DPs single target class like theyr supposed to be and remove those super powerfull AOE spells that they have.
3) Druids - My main is a druid and i gotta say, ever since i got my UE at level 60 thats the only AOE spell i use, since the new ice AOE spell that u get at level 500 or so has a cooldown of 10? seconds, which makes it not really viable in normal hunting and kiting scenarios. Oh, and the wave spell that you get at level 1,5k is utter crap, the single target spell that came before it hits stronger, has no exhaust like the wave and they practically hit always the same amount of creatures which is only 1 (Since people play here mostly alone, which makes waves practically useless since everything here runs way too fast so u wont be able to group them together). Id say change the spell to a single target spell thats stronger then the level 1k one, or make it a new UE. Oh and please delete the cooldown of the level 500+ UE since i wanna be able to play magestyle and group things together and UE them, which is not possible with my lvl 60 UE since it deals only 1,9k damage at level 1,7k. Kinda annoying to see pallys and EKs having better crowd hunting spells then a mage.
4) The bosses dont despawn when new ones spawn, which means there can be ~8 captain sparrows or the swamper, tightly grouped together on those small islands if noone kills them.
5) Dunno if its supposed to be like that but you cant transfer Xp sheets, if u do that they get unusable, no matter by what char. Which is kind of annoying, isnt that all theyr purpose, to be able to collect, sell em or use em to lvl ur noobchars faster?
All in all, very fun server tho, i just miss some more quests and riddles since im nearly level 2k and i only found a single quest so far (I wont count daily quest lmao)
