Have you even tried playing with Scrapper since the new patch? It's not as bad as it sounds on paper. Sure, the F5 abilities are gone, but the function gyro I'm finding to be more effective as an aoe ground target. It was more difficult trying to get the right player targeted before. And the only other F5 I even used that often was the Sneak Gyro F5 which, yeah, I'll miss being able to reveal those pesky thieves who go invisible, but it's not a class-killer by any means. Play it for more than a half hour before you throw it away. Also, Scrapper is meant to be played as a tank. If you have a small roaming party composed of heavy damage dealers and you, you're gonna be just fine.
Someone randomly sent me 30 gold and said, "It looks like you're new. Here's a little something to get you started"
