Just adjust to the difficulty. For the MMORPG GW2 has the best combat system and that should be shown with the creature fight design. GW2 began to storm with flashy effects that make more harm than the bosses themselves, and now Boneskinner is pretty all about mechanics whicb reminds me of old, good times in which you had to use your mind to get the mechanics. Instanced content should be all about different tactics, different approach, abundance of mechanics. If you look at the WoW's Raid/Dungeon tabs which show all the bosses, you can also see so many mechanics to learn, so many things to know, and it's simply fun, especially on the higher level of difficulty. It's cool, because there is fun in tactics as well, I mean that what makes instanced content unforgettable. I could see that, after such a long time yesterday, when the Boneskinner was actually challenging, because it has tactics that you have to learn to notice, and all you must do is to adjust to them.
