Yes, Fel should have slightly better loot. Two weeks ago, someone did a T-Map right next to my Fel keep... because I wanted to have some fun, I brought out my red archer and chased them around a bit... got off a few kills before I let them finish it up. Poor saps probably didn't much from the T-chest, but I have a feeling this isn't the first time something like that has happened. I give the two people credit for sticking to it and not immediately running away with their tails between their legs.
An no - power scrolls should not be offered in Trammel. We shouldn't devalue Felucca and the risk of having to engage in PVP so that everyone has an equal chance because some people get too butt-hurt by taking a death robe at the hands of another player. Life isn't fair / equal, and UO shouldn't be either. But that's a completely separate topic for aonther thread.
That aside... yes, a loot revamp is needed. T-maps, Peerless, champ spawn bosses, etc. However... that doesn't mean ALL of these encounters should drop high intensity pieces on every instance either. There does need to be some encounters which are more difficult and take more effort, to have better rewards... i.e., Lady M and Medusa should not be dropping legendaries at the same rate as Shadowguard or Exodus.
These encounters, in my opinion, also ALL need a serious boost in difficulty. Maybe I am biased in that thought because I play in the largest PVM guild on Atlantic/UO, but many of these encounters are far too easy. If we’re going to scale up loot, then it should have to be earned and not just be a bunch of solo-able cake walks for people to do on some dead shard. Already, we see too many of these complaints that are like “ErrrMuhGawd – I can’t solo every encounter in game with the single character I play and I refuse to attempt any other type of template, play in a group, or do ANYTHING that may potentially change my precious play style or force me to give up my Castle on this dead shard that has SOOO much history that I only I care about.” I have zero compassion for the people who maintain this mindset and want an easy button so that they can play all aspects of UO completely by themselves AND have access to all the same rewards. It's a lot of hogwash.
Also, adding more high intensity items in game will inevitably lead toward deflation of value of the current pieces that are out there, which is not something to take lightly. I think the current in-game economy, while not perfect, is still balanced enough that adding an insane amount of new high-end pieces would potentially throw some aspects into disarray. New players shouldn’t be able to join up and have an uber-suit of all high intensity legendaries in the amount of time it takes for their free trial to run out. Crafting skills are already going obsolete by all this ‘uber-loot’ so that is another consideration that needs to be thought about before adding even more in-game.
