booksarefun666, I do understand your point of view. But let's be honest, it is actually rare that we, the aforementionned balancing gnomes in the secret workshop, do nerf an item. We do not do weekly nerfs for the fun of it. It is done only after careful deliberation for what we believe to be the good of the server. In the thousand+ items in the loot tables, there's bound to still be a lot of items that remain more powerful than crafted gear.
It is a difficult task balancing it all with so many items around. We would not want all loot items to be more powerful than crafted gear, it would render crafted gear useless. In that respect there is nothing wrong in an item being good only to be sold at an NPC merchant, it is still less boring than only gold in a chest. And what you deem unusable for your own char, might just be someone else treasure. Just as we want the loot drop to be enough of an incentive that once in a while you do find something more powerful. As I said it is a delicate act.
Let's take the Casglu'r Tywill blade. The foremost problem of the original blade was its automatic "Lesser Spell Breach level 1" on hit, no DC. As explained in the Item suggestion thread, On-Hit: Cast Spell effects can cause performance issues. Most spells were designed under the assumption that a character could cast at most two spells in a round. When it is triggered on-hit, however, a spell can be cast much more often, potentially twelve times per round. The newer version of the blade still has an on hit property, but with a reasonable DC so it does not trigger on every hit. Even with its defensive penalties, it remains an enchanted blade, dealing extra divine damage, and with the potential to dispel foes. So I much disagree with your stance that it is useless.
If you do feel an item is worthless though: useless as in unusable by PCs, and unsellable to NPC merchants, do flag it and we'll have a look at them. But the items you suggested here are far from useless.
aprogressivist, I know it is a sore spot, but no, it is unlikely we will ever reopen the Vestment of Faith and Oathbreaker Shield debates.
