Topic is about classes like sorcerer and necromancer or which ever class that provide summoning unit. Thus, they are AFKING farm which is like botting. And also people who want to do their main quest and something like finishing mobs kill(monster kill that give reward exp card) are quite hard because of this. I know a lot of people complain about this.
So here is my suggestion. My suggestion is to make time limit/lesser time for the summoning monster. So that, they will less afk. Please take care of this kind of thing. If not there will be another player quit the game.
