Sentient and filigrees have added a problem for weapon mouse-overs. Filigrees, their descriptions, and their set descriptions take up so much space on the mouse-over for a weapon, that it causes the weapon to oh so slowly scroll the things that don't fit. There's no way to speed the scroll (move the mouse and it kills the mouse-over). And, it has a time-out. It scrolls so slowly that it literally never shows the one piece of data that someone might need to see FAST during combat: the item wear bar.
About 90% of the text shown could be removed; eg. "Dexterity to Damage: This weapon can use Deterity for damage." Bit of redundant redundancy there? Some of it is completely useless due to lack of data: "Increased Weapon Die: +(W) damage." tells me absolutely nothing (it could say "Weapon Dice: +3.141W". Most filigrees display two text lines where 1 would do. And, well, the item wear bar is at the bottom -- can't even see it because the scroll times out and ends before showing it and it takes 15s to time-out, too (FAR too long for mid-combat viewing).
No, don't make the scroll last longer. Move the bar so you can see it FAST without any scrolling. Preferably show it even without needing to scroll. Other games with similar systems typically include a horizontal bar on the item icon itself.
IMHO, there's some data that is nice on a fast mouse-over that might be needed in combat: item wear, augments, and TERSE filigrees (for those with multiple nearly identical swap-items -- which one is that again?). Item type and detailed behavior is important for mouse-over checking on new loot. STORY is great, but that can wait for out of combat / post-looting viewing; eg. move that to a right-click for info area that opens a full multi-page novel for all the descriptions you care to add -- or even shows cutscenes of the gnomes and dwarves who toiled away constructing it. Showing all that on a fast check and never showing what you really need to see is a problem, though.
