I don't think any Red Mage can deny that Enspells are fun. However, if the Red Mage happens to be in a party with a Dancer (or even using /DNC), then our job-specific "Sword enhancement spells" start to direly inhibit our front-line performance, since we would then not be receiving the benefits of Samba Haste. Given the way the increasing returns of Haste work (as everybody knows), this is a ridiculously disproportionate tradeoff, and a wise person would forgo the Enspell and take the Haste every time.

The only exception that would make Enspells at all passable is if the Red Mage in question is Dual Wielding (as opposed to using an EX Sword Weaponskill support job) and using an Enspell II with a Dancer in the party.

Must our own abilities conflict so much with a Dancer's that they become nigh-unusable in their presence? Isn't there something else that can be done to solve this conundrum?
