Doesnt work cooldown for Hellstorm.
-34% cooldown - 1 round 0.27 sec
base Concentrated Salvo - 1 round 0.3 sec.
Yet, despite that, Concentrated Salvo shoots more faster than Hellstorm.
WTF??? I test Spin-up Salvo, Concentrated Salvo - on this skills nodes -% cooldown doesnt work too.
Why heavybolter have nodes -% cooldown on this skils, if they doesnt work??? WHY???
Why you do this??? I break my brain! I dont understand - this is useless! I spend many credits to roll thiss nodes - and they dont works. Result - i have nothing.
Kortes is absolutely rights!
And why in game realised -% cooldown on channaled skils???
This is senseless.
I would guess skill calcualtes DPS based on cooldown, despite the fact its channeled skill. So lowering the cooldown of the skill will display wrong DPS, considering this skill is being just normal that is pressed(activated) each time on cooldown.
Like if you have witchfire with 1 sec cooldown dealing 100dmg it has 100DPS, but if you lower cooldown to 0.5sec, it will display 200DPS cause you can press it 2 times a second dealing 100damage each time.
Which is irrelevant for all type of channaled skils
HellStorm - not good skill if it havnt bonus on cooldown.
As @WELEWALA said the cooldown goes only for how fast you can recast the given skill. This does not affect the pace of the channeling. The skills are working as designed.
I think - this is bug - becouse DPS - specify wrong. It influences on gameplay.
One more - why then reduction cooldown on such skills in general is present at a game? - this is wrong.
I think that it needs to be fixed.
The bug you mentioned about -% cooldown ... -% cooldown does not affect how channeling skills perform during channeling, it only affect how fast the cooldown complete after you finish with the skill (in this case, how fast you can cast it again after finishing channeling), same concept apply to all skills that do multiple hits within one skill cast/attack (channeling, rapid fire, salvo, etc.).

May I ask what were you referring to then? What the -34% cooldown represents or where it comes from?
May I ask are you using the Tactician perk which reduce the cooldown of every skill by 30%?
