I don't like BoS, but you do. My points are valid, and so are yours, even tho I disagree with most of it. But one thing remains the same so far, that BoS remains dominant without opening better playstyle for those who don't want it. "Play what you want" is not a thing in WoW for most my man, never was and never will be, simply because to one wants to be gimped, no matter if you raid normal or mythic. Some (rare) guilds are more friendly towards what you like to play, but will still advise you against playing a bad spec because it hurts the group in a way, and I know it well, because my three favorite specs(Feral/Sub/FDK) are underdogs for quite a while now. I still play them no matter what, but I have a more capable toon to progress because I don't want to be the weak link. There is nothing wrong about fixing BoS to be a better talent, and it's not the point I'm trying to make here, not fixing the spec to allow variety is. PTR is subject to change, so until I see it live and can test it for myself, I remain skeptical of how much of a loss/gain it is to not roll BoS. Even then, FDK still needs changes for more engaging gameplay.As an example, if Frostschythe was made baseline and costed RP, Obliteration could be reworked pretty easily to empower your rotation based on what you are doing during it, like FSchythe allowing Oblit to cleave, and FStrike making it hit harder on ST. Icecap could remain a passive option, for those who like a less hectic playstyle and don't mind a dmg loss, because I too agree that easier talents should be less rewarding. I would suggest something more wild, like a full talent row to empower Oblit/FStrike like in the past, but it's too much to ask in the current state of the game since it requires more careful planning, and with the closing of BfA is something we will only see in the next xpac.
These changes still suck, Frost DK is still at its worst condition no matter how good u try untill u get back the old talents and rather make some talents as spell books and add new talents like in Legion was adds on Enhance shamans
