It's tactic based in EoC, as opposed to being black and white before EoC was released. Honestly I've heard that it's died down drastically, but that was upon the initial release. To answer whether or not staking is still possible, philosophically speaking yes as it still exists in-game. However, I wouldn't recommend investing GP and diving in as there could be several potential bugs, etc. but that's a matter of opinion I suppose.
