On the 3rd layer resides the lich Vargoth. He now can easily dispel a lvl 30 Caster with Mordenkainen. He dispelled half of my wards. Usually he couldnt dispel one.
It´s not about FVS. He still was easy killable.... I can rebuff, go ethereal... dont need some buffs. I can recast wards for the Dracolich and still kill him.
I could imagine for a group of "normal build" adventurers its quite dissapointing if the mage´s buffs all got dispelled and he has no one left for the following encounter with the dracolich. A DC Mage/Thaumaturg can probably do not so much against the enhanced mobs in the Vault, since i guess their Saves are also buffed and his dmg output may not be that good as the fighter and rogue. You could argue he can rely on ressources like scrolls and such to rebuff for the Dracolich fight.... They also will get easy dispelled by the Dracolich and he finally will make a gold minus for the whole dungeon....
Overall i feel the Dynamic CR in end level dungeons weakens Normal Builds and Powerbuilds and encourages players to go for Overpowered builds. A FVS got more value, its good against being dispelled. It always was a good class, but it´s better now. Also Clerics with EDM and Divine Spell Power are favored more because they are more resistant against Mordenkainens Disjunction and bring overall more mechanical power to the game than other builds.
These dungeons are now more difficult for other builds....
This effect is certainly not wanted by the new system.
I dont want to hide the "enhanced" loot i found : An empty spirit bottle on Vargoth. I better stop here commenting the loot system, you all know its fun.
To say some nice things about the Dynamic CR System: I like the diversity it brought. Its sometimes fun to see a bigger mob, it may need a feat/spell you wont use else. It´is not a challenge for a simple Powerbuild or an OP build, it is a challenge for "normal" builds. You may be fooled to believe it could drop something nice.
On the other side: As i started on this server as a wizard years ago, i found every map challenging, died endless times.... Had some more fun RP and making friends... Was very disappointing on my Chars global weakness.... The server is already and always was challenging enough for many RP and "normal" builds.
I can see and welcome the need and input of Diversity. But the Dynamic CR System needs a bit balancing, else the idea behind it is good.
The server strategy paper also had dynamic quests as new source of diversity. That could be a solution with more positive impact for players.
Errrm...
