I also dont know why anyone wouldnt want to change Icy Talons. Its a shadow of its former self in any of the forms it existed prior to when it was changed to a stacking upkeep buff that it is now.
In wrath it was 25% for having FF on the target with improved Icy Talons.
In cata from what I can find was attack speed increase by 20%, haste increased by 10%, and 5% more haste stat from all sources. Improved Icy Talons increased attack speed of party and raid members by 10% and increased your own attack speed by another 5%.
Now its 10% less than what we had basically baseline, and it was baseline at one point, and you have to upkeep it. I would rather them just to delete Icy Talons than make a mockery of something that was a staple of a high attack speed spec.
High attack speed was for KM. KM was just procced from auto attacks, higher auto attack rate meant more KM procs which meant more Obliterate and Frost Strike crits, and guess what… absolutely no one complained about the spec until they started messing with the rune system.
Blizzard and quite a lot of people on these forums have absolutely no direction for the spec. They are trying to make it cling to the past while trying to force it in a direction that these things werent designed for in the first place.
Obliterate for example, for an ability that was and is used ALL THE TIME, its base damage is low now thanks to KM rank 2 and ever since it was put into the game there has been complaints about Obliterates base damage. Thats why I suggest another rune spender and just make Obliterate cost nothing and only usable while KM is procced.
Change Frostscythe to replace the new Rune ability for cleave. Yeah, it might be hard to balance but thats what testing is for
Frozen Pulse is also another one of those things that is attack speed reliant in a way with a spec/class that is constantly being slowed down. Why does it exist?
Hypothermic Presence… while what it does it does well… why is it there? Its not needed what so ever. Especially when its up against Remorseless Winter and Glacial Advance… why isnt it just moved to say the Runic Attenuation / Murderous Efficiency row? There is only one possible answer, Blizzard doesnt know what direction to take with Frost and couldnt think of a new talent to put in the place of Frostwyrms Fury so they made something for a space filler.
Icecap, really only synergizes with DW because of how DW mechanics work. As long as a main hand or offhand crits it counts towards Icecap CD reduction. So really DW has 2 chances per Obliterate / Frost Strike to reduce PoF CD while 2h only has 1.
So realistically, in every single row that provides some kind of dps benefit, there is one dead and useless talent.
Could always be worse though, could be Enhancement Shaman.
