not really... it is probably not noticable on rare drops [Blue proced Indrik with Th7-8, 1/4 droped in 20 fights], but very noticable on common ones ( example farming pop items).The other days I farmed ulhuadshi. the first 6 I yellow proced and TH6 only ( THF range attacks). Only got 2 jewels. Next round I proced 6 Ulhuadshi and did TH9-10, got 6 jewels.

I got other examples with emperador de altepa where yellow proced, TH6' d Nms drop almost no seal, while TH9-10 would guarrante 2-3.

In dynamis I got ~175 coins the few times i entered w/o THF, and I usually get 250+ with TH6. Etc.
