About time they'd do something like that. I've been struggling to get any kind of EXP activity going since Fell Cleave burns started. Dominion pages parties are pretty much dead, took me two weeks to get a GoV EXP party going in Crawler's Nest. The top of luck is to see an La Theine shout every few days.
Wish I knew where people got all this money to pay FC burns. I never had that much and if I ever will I definitely wouldn't spend it to EXP, which is something that shouldn't be done by afking (thus the word 'experience'). Because of these activities newcomers are getting pushed away from the game because they don't have the gil to pay burning nor can find someone to exp with.
As I've said in other posts, I think SE should just make Fell Cleave magical damage and nerf it. That would solve the problem once for all. Other activities such as farming dark rings or empyrean boots can be done without it just fine (Personally I do it as blue mage). Let's see if this banhammer brings some life back in previous exp areas.
