Economy is just fine. Shit that was a div before still is a div. Shit that was 45 div before is still 45 div. Exalts inflated, yeah, but thats because they really have no use but that happens in every league anyway 3-4 weeks in.
The Vaal farming shit is really a few people that literally play POE for a living and have the fucking time to do so anyway. Even with the stupid Exploit, which is gone now anyway, it still took shit loads of time to set that shit up for those mad profits.
