Raider rewards are raider rewards; you don't get them if you don't raid. It's impossible for all the different components of the game (flashpoints, ops, crafting, gearing, alignment, etc. etc.) to be 100% independent and if they were then the game would be incredibly boring.
As someone who participates in every aspect of the game, I'm sick of people who don't play the whole experience complaining about how it's "poorly designed". Your self-imposed rules about how you're going to play are poorly designed. I'm not saying you HAVE to be a raider, I don't care, but you should accept the results of how you choose to play. BioWare is not going to meet your every whim at the expense of everyone who's playing the full game and having fun.
