look there way limit the beastmaster it if they use my ideal. first if you limit to pet you only tame in realm reborn and you only reach lvl 50 with it then your limited. see the point for blue magic is after the limit cap is remove you lvl it always to lvl 80. this same truth for beastmaster. by limit lvl cap you give people time figure out the jobs.
think about limit family you can tame

ranger beast

melee dps.
tiger, gorilla,
tank pets. pet that tank base there size and access to high expansion for example
Mammoth, t-rex, tricetop,

this work
heavenward, stormblood both has keep access to some pets limited if your limited to lvl 50

we have summoner we don't need another and even the summoner need work and improvement because it feel less like summoner of early ff games

I rather SE take more hunter route yet make more advance Blizzard simplified hunter way to much and make kind not fun
