Ecstasy IS MDMA. Usually a pill with the active ingredient being of the MDXX (MDMA, MDA, etc) family.
Are you saying a pill with only active ingredient is MDMA is a shit pill?? You need to read up what Ecstasy is if you think otherwise.
Some web sites to look at:

And also in regards to Designer drugs. As I stated, they are drugs that were made to circumvent laws in regards to specific chemical structures. Nothing to do with "hey I want a pill/drug to make me hug everyone all night, or a pill/drug to make me talk all night long and not sleep for 1-2 days.
Drugs are just cause and effect. No one specificially thought 'hey, I want to expand my mind and see many colours. I bet this chemical structure " 9,10-Didehydro-N,N-diethyl-6-methylergoline-8ß-carboxamide" will do it (LSD)
*EDIT* Ok to "No, not at all... im saying a pill without mdma is generally a shit pill" it just seems worded as that 'just MDMA, it's a shit pill". Yes, pills that aren't mdxx should not be consumed
Also the feeling of Ecstasy not being MDXX is mainly for Australian (NZ as well?) As for years, it was hard to get MDXX pills in Australia whereas a lot of K + speed bombs were around which people thought was 'the ecstasy experience'. You'd be hard pressed to find K + speed bombs in big amounts like you find in Australia in other countries. It is good to see nowdays that the majority of 'ecstasy pills' in Australia do contain MDXX and not speed + K bombs. That said, would be nice if it was 100% of "Ecstasy pills" did contain MDXX.
