Yeah basically what we see now with folks requiring blu to have certain skills to run content would be a lot worse if it was a fully open job. Right now its not that problematic since its side content and totally optional, not to mention a challenge, so i sure devs arent too worried about that aspect. As for beastmaster, personally think it'd work fairly well as a full job, picturing a melee smn for the most part, give it a whip or spear, a couple of monsters to call upon maybe a "greater call" that can summon in boss like monster for a short while kinda thing. Think if we do see a limited beastmaster, id just be a lot more "pokemon" also think would use a lot of blu's content, carnival and such, maybe could party up with blu the achievement stuff. Blu as a limited job actually doesnt use that much resources as people make it seem, now that devs developed the learn system a lot..... of it is just reused assets, copy skill from monster, paste on character kinda deal, lol. So yeah if they made the tame and train system, bst would pretty much be the same way.
