How much exp are you getting per synth? 150? Maybe 200 at best?

If you're trying harder synth you'll be getting around 400~500 range exp per synth, those you can possibly blindly spam standard and still get maybe a few successful synth.

However, if you're really pushing yourself and aiming for the 700+ range, you can't just blindly spam synth and hope for the best.

Basically, the people who are taking no risk, are ideally similar to the people who would kill Easy Prey mobs for EXP. Can't complain it's easy because it is easy.
