Should only have gotten better over time. Just have a super geared friend, especially DPS, join and carry. When it scales per player, and you have a person doing more dps than 2-3 people put together, the place is a complete joke.
Depending on what you are after, you can find 3-4 people interested in running. You run 2 groups. First group has you and one other person on their alts, and the other two people on their main. Then you run a second group with the options switched opposite.
This works very well if you are doing Garrosh heirloom farm, but either way is the best option for avoiding failure.
Either way, at this point, if you are upset about flex, its probably time to find a guild.
