Deepwind Gorge Victory

The new battleground released in patch 5.3. Much like the Battle for Gilnaes with 3 nodes to capture and Warsong Gulch thrown in but instead of a flag there's a mine cart full of the opposing teams gold.
Each base controlled earns your team 8 gold every tick (about 4 secs). So potentially 24 gold every 4-5 seconds.
The mine cart when picked up will subtract 200 gold from that team. When captured, that team earns 200 gold. So in essence that makes for a 400 gold swing. Speed built classes like Druids are unable to benefit from dash or travel form while pulling the mine cart although wild charge seems to work just fine.
So which is the best priority? Personally, I'm finding the best strategy is to capture the enemies mine cart while controlling one mine node. Preferably the middle to split the opposing team and to give your FC a straight line path.
