The only real problem with scholar is Titan HM. Two white mages can heal up the massive AoE where a scholar really slows down the AoE healing there. I can't speak for coil but for the rest of the content I prefer having a scholar alongside when I'm White Mage. Also right now stacking 2 regens and 2 medica II is slightly better than anything a scholar can come with. This is mostly from a min/max PoV. Apart from that I wouldn't really consider Scholar as being inferior to a White Mage. More like White Mage is inferior to a Scholar because the only thing we have is really the burst healing apart from that the scholar does it better.
