The mage ability is underwhelming, it's basically another asphyxiate without the stun.
The range one is very good.
I had many discussions with the Ninja team back when the Range buff was being discussed on how to make Range equal to mage. One of the things I suggested was that Rangers needed their own Omni, kind of like how Mage and Melee have Omnipower and Overpower. Rangers only have incendiary shot, which is restricted to 2h (and worse than Omni/Over) thus making it fairly useless. Of course they never did listen.
Now they give Rangers their Omni but make it way better than Mager's Omni.
Why can't Jagex do things the simple way? All they had to do was copy Omni/Over (which are identical) for Rangers, and all would be good. Instead they go the same old route of trying to make things different for the combat styles (while paradoxically trying to 'balance' the triangle), which always leads to a discrepancy with one style being vastly superior to the others. At the moment it appears Range got the best out of today's update by far.
From what little I have heard, the familiars seem trash.
Also, kind of funny how the May BTS said the abilities would be Ultimates, but are actually thresholds (it's probably better this way).
The healing ability is sort of meh as well.
Good day for rangers, meh for magers.
