Not really that enthusiastic about it. For one enemies light up on your HUD, so you will either immediately spot them or they will cheat early on. Now I call it cheating because it's supposed to be near perfect camouflage. This also means that they either don't show up on hud cloaked or simply can't be targeted whilst cloaked, despite you clearly being able to see them hoovering around. If you visually can't pick them out then the term is pointless and they are basically nothing more than teleporting tentacles.
So the match will go kind of like this;
Spot enemy to activate them (after all roaming aliens is not in the budget and too hard for the "modern" gamers), enemies cloak because surprising aliens is also a thing of the past. It's not fair to shoot someone with superior weaponry in the back. Fire fight ensues, suddenly one or more of these things are strangling a squad mate or even several squad mates. Now remember your squad has a max of 6, so that's 1/3 of your squad dead, incapacitated or about to die from friendly fire.
Sounds good on paper, but in execution it will be about as useless as the SHIV, that was a cool idea, but made utterly pointless and redundant by the requirement of it replacing a squadmember. Or the panic some squadmembers could experience early on, which was an amazing idea in the original X-com because you had 15 other guys who could pull the weight, but here it could start of a panic chain reaction incapacitating your squad for no reason.
(If you dare to excuse this by saying "but it's realistic" I will be forced to beat some sense into you. Realism has no fucking place here, do you think the fucking army is going to send out squads of 4-6 to fight overwhelming odds on crucial world wide missions whilst there are literally 40 other dudes jerking off in the baracks? No they are going to pack that chopper with as many personnel and as much equipment to kill them Martians deader than dead.)
