are all ees items worth the same ? or are lightning more expensive than fire for example

very rarely will there be a specific iso for lightnings. 5 is barely usable for a level 20, in general most people are looking for max slots from level 1-20 and then 7+ slots for 25+ will generally just have reasonable value.
Quite similar to EE, where anything below 90ee is generally near worthless.

might get 20 fg, but expect it to sell for closer to 1-10. 5 slot level 10s don't sell for a great deal either

hmm alright ty,
