"a few times a week" is considered pretty insane for even heavy users. I don't think that just about anybody is advocating that frequency of use. Regardless of long term effects I think most people would be feeling pretty messed up by the end of that week. Once a week is sustainable in the short term but I am not recommending that and make no claims as to its safety in the long term. I would have no way of knowing other than googling studies. That being said I'd still like a source for the claim: "Yes but MDMA specifically will mangle your brain after very little recreational usage relative to almost all other drugs."
