That's a very good point. Bosses are too weak, some times u cant hit them before they die, that is so ridiculous.
In my opinion bosses (not talking about quest bosses) should be modified every two years. Do not makes sense to me that that the "strongest" boss in Tibia dies in two turns.
Tibia community has improved alot their skills and strength but the bosses are the same. We had the time the every boss on tibia, or almost all, was very hard to kill but this was a long time ago and Cipsoft must change them. This is are easy to do, have just to create new mechanics, improve their life, strength create some things to the ppl be afraid to fight this boss. And plz make the loot random to everyone who helped to kill.
