Ok so Freezing ice was on 1) Frozen tunic, so you had to wear it instead of armor sets or a something with Vitality of invulnerability etc or on Leopard's Chill (ML7) so you had to find it and have a build able to use that one weapon. Lootgen has Freezing Ice but not until higher levels where it is useless, similar to a few more named weapons with Freezing ice in epics like Icerazor--not worth using.
In reaper you do not want elemental damage (it gets nerfed fast--so this is better than 2d6 cold at level 4), you want the helplessness caused by CC like Freezing ice. So there was a tradeoff, right?
This little ruby changes everything. Any melee or ranged is insane not to use it. Does it proc on spells? I do not know.
How could this have been implemented better? In the past, icy burst kits were for lootgen only. Why is this not a one-time enchantment for a lootgen like festival solar? Then you have a tradeoff. The rare lowbie vorpal would probably be the item of choice for a lootgen with this enchantment. You limit the powercreep though by limiting the uses of this buff. Instead, this is just way too OP IMHO.
Thoughts?
