first i do like suggest thing for these two jobs i don't want to see SE run for summoner and scholar like dog with tail between it legs. SE let be honest if you run for fix summoner and scholar you run for tried fix pet jobs some people Yoshi P like pet jobs. why called summoner summoner if it doesn't have it trusted carbruncle or summon at it back it basic a witch not a summoner. and scholar isn't scholar it doctor

first change summoner basic summon carbruncle to be summoner familiar these basic level summon. figure out what the other mage dps is by balance it out cute dps that summoner does and what her pet does
summoner and her pet does each does 1/2 of what mage jobs do. when limit summon on feild each summoner familiar the Guardian summon ie Ifrit Garuda Titan Shiva and Ramuh does 1/3

if summoner is summoner then one fix the debuff by make them more elemental basic as i have been suggest

summoner summon Carbruncle of elemental
let say you summon Ruby Carbuncle: the summoner debuff change basic ruby be on feild. burn and heat stroke debuff are now debuff Ruby use these now fire elemental debuff let suppose you summon A Guardian Summon of that Elemental Ifrit the summon has chance refresh the debuff and increase the dot time basic how much the Ifrit is on feild, supose the debuff 30 second now they 50 second or 60 second basic on Ifrit be on feild.
lb 3 of summoner is now Bahumat come down and doing mass attack not summoner
