Be glad that you get a chance of free epic loot every week without effort at all. If you want actual raiding gear upgrades, find a guild and work for it. If you don't have the time or patience for that, suck it up and deal with LFR. The drop rates really doesn't need to be any higher than they currently are, you don't really even need this gear for anything other than feeling a bit stronger unless you're planning on progressing further into normal/heroic mode.
LFR was primarily meant for you to be able to experience the content, which you are fully able to do. The gear is a bonus, be glad if you receive any at all.
