New MDMA users almost always look terrible while rolling, that's why raves are generally held in dark venues late at night and with everybody rolling so that everyone looks equally ugly. Plus, when you are feeling that good and are that fucked up, who the hell cares what you look like? That or either they are too fucked up to know how bad they look, which is sometimes the case as well. Ignorance can be bliss.
However, as your tolerance develops over time you will look less e-tarded while rolling, but the catch is that you won't be rolling nearly as "nicely," as you put it, as you did before. That's why certain people at raves look normal, sometimes even a majority of those in attendance: their days of no MDMA tolerance is long gone. Never fear, though, having been through that phase before they are generally tolerant and polite to the young funny looking rolling kids. Sometimes maybe even a tad bit envious, not of the way they look but of the way they feel. Plus, dilated pupils are rather attractive.
So, to answer your question, sorry no, you can't roll nicely and still look normal. There used to be a saying around here that PLUR stands for People Look Ugly Rolling, but my favorite raver acronym is BURP which stands for Bring Us Real Pills.
My advice to you is to just enjoy your roll and realize that your ugly looks are only temporary. After all, as Tricky puts it, "When you get older, your body won't look so good." Beauty is, by definition, ephemeral and only skin deep.
