Have you noticed the charges on Cyclone btw? It seems to subtly grow in area (at least that was my impression) as you keep channeling.

EDIT: Plucked some data from the videos.

The gem tags are: Attack, AoE, Movement, Channeling, Melee.

• The mana cost is 2 (down from 12).
• Damage effectiveness starts at 45% (no change).
• Default movement speed multiplier is negative 30% (no change). But the skill now has several (allegedly 4) predefined multipliers to movement speed depending on how far the cursor is from the character; if you aim at yourself you will cyclone in place, meaning it's now possible to take advantage of Arctic Armor and the like.
• Attack speed has a 200% more multiplier (up from 50%) (EDIT: Seems it's just a cosmetic change to compensate for the fact that Cyclone does not actually hit twice per activation anymore).
• No change to requirements at gem level 1.
• First hit still deals 50% less damage (not sure what it's needed for at this point).
• The skill gains stages (?) (up to 6 has been seen thus far). They seem to subtly increase AoE as you keep channeling, and have a short decay timer upon interruption, akin to Worb and other channeling skills.
