I know, right? The adrenal implant also looks neat. They all look neat, is the problem. >.[
Adrenal implant is effectively a temp. strength boost when needed, and a slight bullet-time effect, right? Or am I remembering something else?</quote]Assuming its the same mod that the Soldier class gets in game its basically a bullet time power with bonus damage because you can aim better. The advanced versions allow either better bullet time or damage resistance. ME3 adds Melee Damage or Duration, and Shield Boost (wtf?) or the ability to use one power when its on (equally silly). The mod basically allows you to go into "the zone" at will with a cooldown, for your health amongst other things. Having spent all of 1-2 seconds in the zone due to a near car wreck I can tell you its the most badass feeling ever, shits going down, you know what to do, you do it. The maxed out ME2 version allowed you to spend around 62.5% of your time in the zone, ME3 wisely dialed it back to 45.9% of the time.
It's actually not the best thing to give to someone young I think. I do believe that the implant should also help purge the adrenaline, but over overexposure might not be good. There is a reason the implant was restricted to those with high constitutions in game (or that could just be game balance

). Some one who knows medicine/biology could say more.
On top of that we don't need it immediately it'd be nice if we saw combat often and it might sell well but we have other things to do, so it goes in the I'd like but we don't need right now pile for me.
It come down to balancing need, want, cool, and Awesome but impractical (I'm looking at you transforming 500m mecha).
