You guys do realize that network hashrate is highly inaccurate. It's not like the pools broadcast their hashrate to the network and the total displayed. The network hashrate is based on thr current difficulty and thr average time blocks are found. If the network is highly unlucky the network hashrate can display a value lower then the sum of all the pool hashrates. If the network is highly lucky the neteork hashrate can become really inflated

Network hashrate isn't a good measure to calculate pool dominance. You need to look at pending blocks for that.
Minexpool has around 75 percent atm. Still a bit high but I can't control where people mine. It's not up to me to police.
When price increases again. People at suprnova will again start mining mnx and the hashrate will be spread out once again.
