Try using the dimension expander instead of the reverb! And layer that with a bit of chorus.
When it comes to synthesis in general, a good way to improve your skills is to NOT use any FX. This forces you to hone your technique with the actual synths. Remember, a lot of the original modular folks didn't have reverbs/delays/distortions to play with. They had to make great music with the synths, nothing else! It's a huge challenge, but you will get really nifty with your synthesis techniques.
Some fun techniques you can use (apologies if you do these already):
-Use the feedback knob with some aggressive saw waveforms
-Use two wavetables, and detune them to the point where you can hear the volume oscillating (more obvious at lower frequencies)
-Put a bunch of different, non-synced LFO's on the "intensity" and "waveshape" knobs on your wavetables
-Create a custom step sequencer! And then see how many different parameters you can use it on
-put different wavetables through separate filters (massive has 2) and then run them through envelope generators! you can make cool laser sounds with this.
That being said, I've gotten sick of massive lately. It's so valuable to know, you should learn everything you can. But there are much greater tools out there
