What's wrong with multiple lines per license? Toy Companies are just trying to market to very different segments of the population. Why limit diversity, simply because one person doesn't like something. That's not how things work, no matter what you're talking about. Not everyone is going to like the same thing. That's the same reason that comic publishers publish so many books. So there will always be something on the racks that appeals to different people.
Why do we need Superhero Squad? Cause it's a fun easy to collect toyline, that's made with little kids in mind but has enough grown-up appeal to appeal to the adult collector as well. That has managed in just a year to offer an incredibly diverse collection of characters, many who took years to be released in Marvel Legends. And next year is looking even better. And which is at a decent price point so that even the poorest kid can get a fun toy.
How exactly are they a waste of your hard earned money? Unless you're telling us you hate them, but for some reason buy them anyway. That wouldn't make a great deal of sense on any level. It's not like someone at Hasbro is holding a gun to your head and forcing you to buy them. It's your choice to do so. And while you claim you're not trying to be harsh about it, you're coming off as incredibly condescending to anyone who does like the line.
I for one buy them because they're what toys are meant to be. FUN. It seems that so many adult collectors don't seem to fathom that toys arn't meant to be collectable or for adults. They only became that thanks to companies like McFarlane. They're supposed to be fun for kids. It just so happens that those of us without kids choose to collect them, not for the sake of blowing money, but just because we happen to enjoy them. They're the best figure line in decades.
Superhero Squad is Superhero Squad for adults. Period.
