Multiple Traps

I dont know if this Thread is the right point to give a suggestion since it is inactive for over 1 year but I just realzid (while planning for Atlas) that there is a discrepance between Multiple Traps and Cluster Traps. Correct me if im wrong, but it seemms that Cluster Traps should have a higher Mana Multiplier(150) than Multiple Traps(160) since it is a greater "enhance" to the spell itself.
