I personally like the cooldown change because this forces players them to learn more than 1 combo to fight in pvp or make a build that's more adaptable.
this cd change prevents certain class from being 1 trick ponies.
for example fighter if you wan to go full dex that's fine but youll need more then just 1 needle combo to win try mix it up use thunder, or charge rp ball and kd with energy barrage.
Also the cd change affects everyone. karmas cant spam shout as easly! so cant sks 45m stun be as spammable, sometimes with full cd gear before this update sk could land 2 45m stuns. cranes will less likely be able to use there 1k slashes more than once a match (I have dones this in a few matches in the past pretty lame of me I'm glad this is gone it made cranes too op).
this change is cd doesn't ruin any class in particular. it just forces everyone to become innovative. dish out different combos and make pvp interesting and less predictable.
This update will separate the less experience players from the more experience ones.
the only ones who complain about this change are players who don't want to change their style of play or cant adapt.
In short Cooldown change made earlier today is way more beneficial, makes pvp more interesting and less boring. It forces players to learn the game more and be innovative
