Xikanir's Ring Quest is a great quest that every player should do, it results in a great item with excellent clicky effects. Depending on your class the clicky effect varies:
Ring for the Spiritual
Unique Clicky effect: Chaotic Spirit
Ring for the Strong
Unique Clicky effect: Chaotic Defense
Ring for the Wild
Unique Clicky effect: Chaotic Wildness
Ring for the Energized
Clicky effect is NOT Unique: Power Potential III
Items with this effect
Ring for the Energized
Crystal of Potential III
Glyph of Power
Immaculate Loop of Energy
Glyph of the Burgerz
Lucid Rune of Destruction
For three classes: tanks, healers, and melee the clicky effect is unique. Hence the ring obtained remains useful for as long as you play on THF.
However, the focus of this post is on the casters' ring: Ring for the Energized. The clicky effect for casters is NOT unique, Power Potential III. If you click any of the items, then none of the other items with this effect can be clicked until the recast time has passed; they are all on the same timer. Not only that but the recast delay is less for other items than for the Ring for the Energized. So the casters' ring becomes obsolete as soon as your caster gets another item with the clicky effect. The ring gets put in the bank or given to a bot or something.
What I propose is that the clicky effect for casters does not become obsolete. The casters' ring would then not become obsolete and, like other classes, would always remain useful. The easiest way to implement this, I think, would be to simply make the Ring for the Energized be on its own unique timer. A harder way would be to come up with some different, but always useful, unique clicky effect.
