My take on fixing Summoner
My main in FFXIV is Summoner. I love the traditional FF Summoner. However, I don't feel that FFXIV captures the essence of the job as played in every other FF game. In an mmo, there are definitely benefits to the dot caster play style. So, I am not saying this is bad.
There are aspects that have to be there (eye for an eye/physick) for the sake of scholar. But, Arcanist is built around being able to level with damage utilizing carbuncle. I have taken an effort in remaking some of the Arcanist/Summoner abilities so that the play style is more traditional while keeping most of the current mechanics. I have not focused on scholar at all, but I believe this new Arcanist ability list would keep Scholar intact (except with an option of utilizing Carbuncle for some dps instead of being forced to use Slyph for healing). In other words, give Summoners and Scholars Carby if they want to use it rather than other summons.
