There are many spells in a Red Mage's arsenal that never see the light of day, and I seem to recall reading a dev post that stated a hardcoded limit to the total number of spells that can be in the game. No doubt they will devise a workaround for this eventually, but until then I would like to suggest reworking some of those spells that go completely unused so that they are actually useful.
I would like to start out with one spell in particular, or more accurately, six spells, that are completely useless in virtually all situations. These spells are of course the Tier 2 En-spells.
As far as I know, no one uses these spells for anything. Ever.
This situation can be very easily remedied, simply remove an arbitrary and completely unnecessary limitation.
In case you don't know, En-spell IIs only proc on the first weapon swing, excluding off-hand and multi-attacks. This limitation alone makes these spells completely worthless, especially so with the high level focus on multi-attacks and dual wielding.
I'm sure this request has been made many times before, but with the recent influx of melee oriented gear made available to Red Mage perhaps now they might be willing to listen.
There is absolutely no reason for these spells to be limited in this way, and it would not make a huge difference in anything if they were fixed.
TLDR - Please fix En-spell IIs, or just delete them to make room for new spells.
PS - Feel free to post about your own useless spells, who knows maybe someone will listen.
