I had my first KHG Set on a KDF Engineer so i never noticed this behavior before,
today i got my Adapted Maco Pulswave Shotgun with Grenade launcher on one of my Fed Tactical Chars and i had to notice that the secondary attack from the Gun puts my Photon and Smoke Grenades from the Kit into global cooldown (roughly 5 seconds) !?
Who the hell thought THAT would be a good idea?
Also vice versa when you throw a Photon Grenade first the secondary attack of the gun will go into global cooldown... obviously.
I dont know about you but i usually open my attack with a grenade and then follow up with the secondary of the rifle, not possible here and it makes me nuts.
I didn't even pay attention to it ever, it is just how i play, now that i cant do it ....well i notice it and it sux! lol
There is even a KIT with 4 grenades, if you use that the gun can in theory be constantly on cooldown...
*swaps back to Antiproton Pulswave*
*gives Adapted Maco set to BOff*
*wont spend any dilithium on the other 5 Tac chars for this set*
There are other similar effects to this. Try using Orbital Strike on your engineer, then fire the secondary on a standard Pulsewave Assault. Orbital Strike puts the secondary on a global cooldown. I think the idea is to limit how much AoE you can throw down on the ground at any given point, although I can't recall if I ever saw an official dev explanation for this. Still, I kind of think it's intentional.
