I would like to see Legendary Gems that focus on class skill runes. Why not have Legendary Gems that help you focus and create a more powerful build around a certain skill rune.
For example:
Gem of Frozen Orb
Frozen Orb Gains 1% increased damage per level.
Secondary Power at Level 25:
Enemies hit by Frozen Orb have a x% chance to be frozen instead of chilled.
Do you intend to create a gem for EVERY rune of EVERY non-primary skill? At very least that would inflate loot table beyond what is reasonable. And then there are issues with designing, coding them and whatever else.
For example:
Gem of Frozen Orb
Frozen Orb Gains 1% increased damage per level.
Secondary Power at Level 25:
Enemies hit by Frozen Orb have a x% chance to be frozen instead of chilled.
Elemental variation (arcane, cold, fire, holy, lightning, poison, physical), though, are somewhat feasible, though.
And may the odds be ever in your favour.
