Guild Wars 2

Before the patch I believe smoke bomb’s tooltip said that it had a duration of 4 seconds and an interval of 2 seconds, meaning it pulsed blind every 2 seconds.

It now says duration 4 seconds and number of pulses 4, meaning blind pulse every second.

Did we get ninja buffed or was the old tooltip wrong?

I believe the tooltip was wrong. I remember it pulsing every second but I could be wrong. I haven’t used bomb kit in a long time.

Nah they fixed a bug causing it to pulse less. Like they fixed a bug that caused all turrets to have lower damage and bigger hitboxes.
Just like guardian symbols were bugged a while ago and the animation and damage were both smaller. Fixed.

Just a wrong tooltip, it’s still just 3 pulses. You can test it easily with the Steel-Packed Powder trait, as it only applies 3 stacks of vulnerability.

Also, there is no bug with the skill. Smoke bomb was officially changed to 3 pulses in November 2012:
