You definately should be taking more than 1 pill unless they are just some bombass pills. The only pill that had me rolling balls off of just one was a purple ferari, but every other pill I've had to take at the very least two. Also, unless you do alot ex can be kind of subtle when compared with it's reputation. Especially if it is real MDMA in the pill, at lower doses unless you know the feeling your looking for and you don't approach the experience the right way then it can feel as though nothing is happening.
MDMA is one of those drugs where unless you do enough where the effects are undeniable, it can be easy to feel as though you aren't on anything, especially if you're expecting an experience that is different than the effects of MDMA. It's kind of like tripping in that you have to learn how to roll before you can truly roll. For instance there is a common myth that goes around that some people don't get high the first time they smoke weed. I did, but I had to smoke enough to where the effects were undeniable. I remember acting like a dumbass and constantly acting people if I was high. I was, but since I had never felt what it was like to be high I didn't really understand what was happening. I believe it's the same way with numerous other drugs.
Next time I would take more than one pill for sure, and then also realize with pills that any number of substances could be in the pill, amphetamines, meth, caffeine, Pipes, DXM, Mephedrone, MDPV, Methylone, MDA, and hopefully MDMA. Just about every pill gives it's own unique roll, that is if you roll at all, they can also be straight bunk, and without an experienced friend having taken the same pill from the same batch or a tester kit you really have no idea until you take it. Even with a tester kit, it's not going to tell you the complete chemical makeup of a pill, but it will help steer you away from the nastier shit people will put in pills these days.
Also realize that just because a friend might have had a really good, just throwing a pill name out, playboy that was the same color as the one you happen to have, doesnt mean it was even made by the same person, let alone guaranteeing that it's good. People copy the logo and color of good pills. A while ago a bunch of hello kittys were going around, they were all straight speed to begin with
, but even though they all had the same appearance and were going around at the same time, there were some that were shitty, and there were some that were just straight bunk. So, even among bad pills, you can never be sure if there's even worse copycats going around.
My advice for getting the very best rolling experience is to first and most importantly get some pure molly. Then, gather together with a few of you're very, very, best friends in a place that is comfortable and where ya'll won't be disturbed, and bring with you a person of the opposite sex that you have known for a while, care a great deal about and who you have feelings for(good idea if you know for sure that those feelings are returned). Play trance, dubstep, post-rock and modern classical music the whole time. You will find that you're relationship with each and every person there will become so much deeper and wonderful then you could ever imagine. That to me is the true power of MDMA, it's ability to bring people so close together.
