Thanks for detailed answer Gnomi.
You save us from the trouble.
If fx stays for sure, I just wonder, could be for example added some more correlated pale tone of fx colors to different factions then?
For example, Gondor to have pale white fx (correlated to new forged blades, correlated to shine of new blades), Elves keep current pale blue (new forged blades but also some properties of magic weapons for Elves, Noldors in the first place), Mordor stays with pale red (some kind of "slaughtering bloody" weapons, if there is any forged upgrade
), Isenguard pale gray (correlated to their new steal weapons produced by their new industry), Dwarves could have pale white, gray or yellow, etc.
It is just random thought of mine.
PS. I just saw Ea's comment, but have to post this anyway.
Best regards,
