That would make sense lore-wise, but it makes no sense as a gameplay element.
Also, the power description says "become invisible", not "become slightly harder to see, but get killed nonetheless".

I also don't remember cloak being this bad.
It's especially noticeable after ME2, where your cloak INSTANTLY makes all enemies lose sight, and you can literally walk up to them without any reaction on their part.
Now I got mowed down by three Cerberus guys on Mars with an active cloak, but then again, at times, it works as I would expect... Something is definitely not right.
I could get behind the added difficulty of them taking some shots in the general direction, but my Mars experience felt like I was perfectly visible while moving around. Dunno, could have been a very random and very unfortunate coincidence with a squadmate lining up right behind Shepard?
