The Squiffer is legit, quit acting like that's debatable.
What I'd rather debate is that the New Squiffer is actually better than the Classic. I don't think the Bubbler works all that well with a charger, seeing as if you have need to shield yourself, you're probably getting shot at, and if you're getting shot at, you're going to be bounced around seemingly randomly and this can mess with your aim. If you're a charger and you need to shield yourself, odds are it's because you've got multiple opponents with their sights on you, and you can't pick them off one at a time; in this scenario, I'd much rather whip out an Inkzooka and blast everyone to puddles than shield myself and try to work my aim around everyone shooting me.
Also, Ink Mines aren't the greatest, but really, I don't see the value in Point Sensors at all.
