Match up disaster.

So sick of grand arena matchups. I always get paired against people with 7* full geared Treya, wampa, gk, you name it they have it. Fair pairing my eye. I have two whole wins since grand arena since it started. I am the strongest player in my guild, (leader) and we just started unlocking gk in heroic tank and not even close to heroic sith yet but farming for it. So how can I compete with players who are fully stacked and obviously sandbagging in order to keep gp low. I am just wondering if anyone else is dealing with this and how is this "comparable opponents" when it's a slaughter. Not even worth the effort or time. I haven't been given a fair shake since this crap started.
