All frames aren't too hard to get. Since plat prices in Warframe are seriously jew, try to avoid buying earnable things in the future. It's not too bad since you are just starting off though.
Yeah, i've got the Oberon and Equinox Blueprints right now and I'll just craft the other classes, I just wanted another frame to add some variety to my gameplay so I didnt get too bored with just one frame.
You could at the very least use most of them to club someone to death, so I don't know what you mean "completely useless", you're mixing it up with non-functional or just cumbersome as all **** , but yeah you could use them to kill someone still, just like you could use a chair leg or a rolled up magazine to kill someone.
How come whenever something like this is posted the comments are full of people saying "these are impractical" and "these would suck in a real fight". I mean, nobody ******* cares. They were posted because they look cool; whether or not they're actually practical doesn't factor into it.
A weapon is only as useless as it's wielder, so yes, in your case all weapons are "useless weapons". Anyone else can at least bludgeon a ****** to death with one.
My mum is like 95 and dead mate and lets be honest, she wasn't a looker when she was alive, you can do better. Just have more self confidence and you won't have to find your next lay already 'laid to rest', that ****** just nasty. ;)
