Duration does not guarantee success on devices on tough maps/tough zones.
But I know I can be of great help for tough devices with this tool.
For me TC on duration is more of a Joker, a card you pull when things go bad and it's also me sacrificing a bit of damage bonus so that I can best serve the team if they need it. Same way chosing damage can also help your team.
If pugs had a good sense of how to behave during devices, considering the map, faction, difficulty, other palyer's kits, or even the mission itself (it's not so rare to realize you're doing all devices by yourself while your team is just having fun)
If that was a reality I wouldn't rely on duration for devices but let's face it, when does that happen with pug ? Hardly ever...
If you're not doing it right then yes , duration can be tough on your teammates, but guess what, that goes for anything.
Like Arkhne said, it's only a tool and I wish most players would realize that.
I keep hearing that this kit, weapon, power, spec or whatever SUCKS, usually with the associated idea that anyone using the thing in question also SUCKS.
If I listenend to all the complaints I've read about specific things , I don't thing I'd be able to use a single kit.
Players like to blame relatively neutral things instead of understanding that there is usually a good, bad or even average way to use those things.
Then, players will blame you for the bad things they experienced when YOU didn't, like that guy who goes to LZ at the beginning of extraction and then insults you for not going to die with him.
Duration is an ace up my sleeve as far as I'm concerned, I'm prepared to try to align with other player's behaviours on a match, or even to reassess my use of a kit/power if I hear something relevant. But my teammates need to do the same, if not, they'll blame me when s*** goes down and I'll laugh at them. No matter how much you try to adapt to other players in your team, if they don't play along you're gonna hit a wall enventually.
I'm highly confident in my own ability to use the cloak with duration, I know this power, in fact, I have my all life.
When I was a kid, wherever I went, people used to not notice my presence AT ALL, I tried so hard to get people's attention but it's like they dindn't even see me...So in a way I've always known what it's like to be invisible.
(That last statement was for the sake of comic relief, hope it worked, fortunately it was pure fiction, thank you for your concern if you've been touched by this heartbreaking story).
