There are planty of RPg players in tibiantis hungry of new challanges.
Based on anniversary token example, there is one idea which commes to my mind to improve a bit current gameplay by new boss raids.
In my opinion, the last event that ended in thais was one of the nicer / more interesting events I have been to (especially since it was put on the server at 7.4). additionally, I think that each of the monsters at the event was thoughtful and cool. some of the mini-bosses I managed to kill were medium demanding but I bet low level characters wouldnt be able to kill some of them. I think that having such an event somewhere already created, the administration has a lot of room to show off by constructing new ones, because it already has some vision and established habits.
Resp time: Random, taken into consideration monter class category.
here I might add that a nice option would be where some NPCs would say some message about the boss, I mean when the boss shows up he would throw some magic words.
For example :
Santa Caluse about Yeti: I saw a large white hairy beast
at the moment we have 2-3 Bosses and one sensible raid, personally, if it would be from 15-20 random bosses, it would definitely diversify the game, I will say that I would definitely do it myself and check if I can find something interesting
