If you play ME3 on insanity many enemy's still can "see" you if you're cloaked, especially if they see you engaging the cloak, meaning if you go out of cover and clock in the full line of sight.
That was not different in the original game and makes imho perfect sense.
The cloak is also not preventing auto targeting weapons such as missiles or direct damage powers to hit your Shep even if she/he is cloaked.
I personally don't see any difference between how the cloak worked in the old games and how it works in the MELE, at least not on insanity.
All of my "main" playthroughs of the original trilogy were as an Infiltrator (as recently as 6 months ago), as was my first playthrough of the Legendary Edition, and in my experience the Tactical Cloak functioned the same in both versions.
I usually activate the Tactical Cloak from cover and use it to run past (or away from) enemies, and unless they're shooting at my squadmates or I run toward where they were already firing I don't have any problems being shot while cloaked.
EDIT: And now having viewed this clip where someone demonstrated their usage of the Tactical Cloak, that's exactly the behavior I expect. They use it out of cover while being shot at and barely move from the location they activated it. Still being shot at in that situation makes sense to me, and is as I remember it in the original games.

That's my clip, and you're looking at the wrong part - I didn't trim the first part where I'm simply stupid and think I'm fighting the last enemy, then get shot in the back by another one. My problem is with the start of the next round: at the end, I'm getting killed while being cloaked BEFORE the enemies even spawned. They completely disregard this, and know exactly where I am.
Also, as I said, melee-based enemies and flankers will also always know my position exactly.
I'm not talking about "I cloaked in the open and did not move", I'm talking about my cover being rushed by husks, activating cloak, getting out of there, then seeing them follow me just the same.
While I don't really have time to test it myself, I've found this video.
By looking at this one, it feels like you guys are right, and this was the case in the OG version as well, which is weird, because I'd assume that this is something that would have irritated me even then.
It's a bummer though, because it feels extremely broken. I could get behind the fact that they keep rushing or shooting at the same place where I disappeared - but I cannot get behind the fact that they are tracking me as if I'm completely visible. This applies to mindless husks, or the most basic Cerberus footsoldiers, so it's not even like "oh yea some enemies are special and see through cloak". Also, fresh spawns really shouldn't know my precise location (not just in the Armax Arena, but all through the game it happens)...
The game does not reflect on this one bit. If anything, it is totally misleading, as the ability's description says "become invisible". In addition, this makes the enemy sound cues all wrong (and also misleading), since they loudly exclaim that they have lost visual, all the while blowing you to bits.
It is especially noticeable when playing right after ME2. It also feels highly inconsistent, so there still might be some underlying issue.
It is true that there is a vast difference in how the cloak works in ME2 compared to ME3.
But I always thought the ME3 implementation was much more realistic, especially when you look at how you can "see" cloaked enemies.
I also don't think the cloak is worthless and I did half of my playthroughs as an Infiltrator.
Use it for the damage bonus, use it for retreat or flanking, make sure you engage it wile are in cover and don't use it for frontal attacks and it is really beneficial.
