Hi Miwashi, I think your current pay is slightly below average. And the last drawn is an important factor in determining your renumeration offer.
Unless you have really strong passion for the new job, I will certainly not accept such a significantly lower pay. It will not only be a step or two backwards, but also become a resume stain. Future employers will certainly judge you negatively for it.
Besides, in this current tight labour market you should be aiming for higher, not lower.
