Skill: Song of Mana
Pre-patch formula: regen 10 SP every 5 seconds, +2 SP for each additional performer over 2 (total of 30 SP per 5 seconds with 12 performers).
Post-patch formula: regen 10 SP every 5 seconds, +5 SP for each additional performer over 2 (capped at 35 SP per 5 seconds).
Why I want to see this skill changed: Let's face it, on iRO there will never be 7 performers in a party to reach the 35 SP regeneration, nor would there ever have been a chance to have 12 before the patch. Additionally, Magnificat provides a better buff as it effectively doubles SP regeneration by halving the regen times to 4 seconds while standing and 2 seconds while sitting. Yet Song of Mana requires two performers. Consider one of the three following options instead:
A) Skill recovers 35 SP every 6 seconds. Each performer over 2 reduces that regen time by 1 second at a cap of 7 performers for a total of 35 SP recovered every 1 second. Swap the re-use delay (90 seconds currently) and the duration (120 seconds currently).

C) Skill recovers 20 SP every 5 seconds. Each performer over 2 and up to 7 increases regeneration by 10, for a max of 70 SP every 5 seconds. Again, swap the re-use delay and the duration.
Or any combination of the 3.
