There is a difference in nerfing something and completely removing it... Like I said I agree WW (and archon for that matter, but I don't play one) needed to be nerfed, but, based on the datamined stuff they aren't nerfing WW they are outright removing it. The synergy between the skills is literally being removed and turned into something else entirely.
That's not a nerf.
The play style should be allowed to live on since it's a lot of fun, they just need to put it in line with everything else.
Killing it off is putting it in line with everyone else. Noone else runs around with everlasting run speed, insane resource regeneration, extremely high damage, CC immunity paired durability (partially due to the the way their main stat works amongst other things), the ability to move through enemies (so as not to create a problem when surrounded) and a great selection of fantastic passives.
No other class can match it. The class as a whole is just way out in front of the others, and the WW specs in particular were just out of this world. The only think I can think that comes close is the Crit Wizards with tornados that can perma freeze everything, and even they ate a nerf a short time back on proc coefficients, and they will probably get even more.
Im just not seeing what you wanted them to do, the combination was far to much. They may have decided to let you still spin around, and drop tornados, but they would have lowered the damage considerably or the proc frequency of the tornados. Or maybe just removed the ability to pass through enemies and fixed the duration of WOTB. Either way though the build wasn't going to survive in any recognizable form.
