blue mage does have depth cause there is not just one way to play the job so it works. because of that its chaotic with everything it does ie cause it is a limited job. it does not flow into smn cause it has a forced play style (unlike every other caster) where you 100% have to follow the flow without adjusting timings. also you also fail to realize old smn was also a SUMMONER it might not be a traditionally summoner in terms of older ff games but neather is drk or sam (sam being a tank in old games and drk being a dps) im not saying that the idea is bad. im saying that that the just adding summons will not fix the glaring problems with the current smn class ie the complete withdraw of what drew people to play old smn the half baked an forced rotation that is ridged as hell, and the fact it no longer fits under the category as of caster (like adding more summons could work as long as its with another class rework)
it would have been ok with some withdraw but they took away abit to much without adding anything to fill the void, weaving, hard casting, bahamut and phoenix actual being 2 different things, and management. people would be ok with the rework if it had more connections to the other casters and what made old smn good not the dots but the ceiling. you can make an easy class with a high ceiling of improving. smn right now has none. the only way to improve is just rng procs on crit
