[Mass Effect] Arent heat sinks a step back in weapons technology?

I love my old school Carfinex hand cannon. Years of trigger discipline and shot control means I can shoot evenly paced shots all damn day with out ever having to replace a heat sink. Not to mention the ability to eject heat into a charging vorchas face before i can get my omniblade out.

These young guys just joining thr yellow suns are all about these new heat sinks though. They fire are quick as they can as much as they can untill that sink is full and then it pops it self out. Id rather carry some extra gernandes on my belt over those things any day.

What gives gun manufacturers?

Heard of world war one back on old Earth? Trigger dicipline and shot control, even from veteran troops, doesn't hold up well against rapid automatic gunfire.  
The trigger dicipline and shot control that frankly can't be expected of even veteran soldiers in a firefight, especially not close quarters.

If anything, this lethal experiment have been going on too long. God knows how many of our guys died in this absurd experiment in leaving soldiers defenseless with an overheated weapon instead of slapping in a new heat sink and continue laying down supressive fire.

Abandoning brass cartridges was abandoning centuries of arms developement, yet nobody bat an eye.
