Don't really see the issue; I have been using KHG for many moons and the grenade launcher is a more powerful Photon Grenade than the one on the Kit. Grenades share cooldowns I don't know why you expected to be able fire 2 photons at people; those things are powerful!
No, it doesn't make sense that the KHG pulsewave grenade puts kit grenades on cooldown. Because one is attached to the gun and the other is... attached to your kit. When you squeeze the trigger on your weapon, your security team doesn't get beamed in; they're logically totally different systems.
And I'm not entirely sure it's a deliberate way to limit AOE, either. An engineer can use his mine, bomb, and then orbital strike, to create thousands of AOE damage in a very brief span of time. So. I think it's more likely that the secondary attack is flagged as a grenade so that it can benefit from the grenade skill but that the game takes this a little too literally and thinks you're throwing them.
That's ridiculous. Then again, I thought the same thing when they put all the grenades on a shared cooldown. Most of the fun of ground combat with my TAC was throwing all four grenade types in rapid succession.
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*
Who would think that limiting the fire so that you cant mega buff then fire then throw a shield bypassing grenade at your target was a good idea huh?.. :p
And grenade satchel kit, is a dud kit regardless of the gun
