Would u buy regeneration potions?

[NotMyWay]

For those who dont know, the potion production skill can create 2 potions at 150 skill (all tier 1)

HP regeneration potion:
regain 12hp per second for 15 seconds
(total 180 hp)
Regular hp potion heals 250 hp

Sp regeneration potion:
regain 11sp per second for 15 seconds
(total 165 sp)
Regular sp potion heals 230 sp

Obviously, regular potions heal more hp overall, but regeneration potions require more skill, and also they restore hp/sp over time. would anyone buy a regeneration potion and how much would u be willing to pay, and how much is that relative to regular potions in ur server? thank you.
