You personally guarantee it, do you? Outstanding.
I have been taking MDMA regularly for about 10 years. During that time I've went through periods of taking it weekly, more than weekly, monthly, not at all for a few months at time as well as two separate breaks of over a year each. None of the things you have guaranteed to happen have happened.
You are wrong.
Two quick things to consider: Do you test your pills? You can "roll" on some piperazine pills or some methylone molly (or any ridiculous combination). Personally, once I finally got a test kit and found a reliable source, I noticed pretty much everything I was taking previously was cut to hell, hence not too bad of a comedown and what not (if it's cut to shit, or cut with something worse, such as meth as I re-mention in a quote from the moderator before.

While MDMA has never been proven to be "neurotoxic"(Due to numerous conflicting studies), many additives to the drug made to make its effects more potent are. If you have consumed (meth)amphetamine, it is most likely that you have done some brain damage. Otherwise, MDMA by itself down regulates serotonin for a fairly long period of time.
Second, every individual really is different in this regard is...I've seen people do pure ecstasy many times in a month and be fine, yet, for the majority of us, it can cause major issues. It's awesome at first, of course, but then the Brain zaps and major depression hit in. No fun at all.
No one is trying to preach to you, we're just trying to help. Some of us have been there and know what can happen, and it can affect your life as a whole (job, school, family, gf, wife, etc). Keep those things in mind and be safe, brother.
EDIT: Also to mention, and someone correct me if I am wrong, nuerotoxicity is never acute; you feel depressed the next few days or so as a result of receptor downregulation and a resulting loss in tryptophan hydroxolase, which can cause your serotonin levels to replenish much slower. Nuerotoxicity, as far as I have gathered (and again someone correct me if I am wrong) expresses itself in more subtle ways throughout a duration of time, depending on the duration (memory, emotion, motivation, happiness, etc).
