Curious, what did you not like about Sam from 11? I rarely ever hear from Sam players that disliked the job. I was a monk main so I actually liked monk in that game but dislike it in this one (granted I don't have it leveled past 40 yet) primarily because it lacks the unique defensive measures from games of past, the counter.
I hate how it got the preferential treatment in XI. Every update would be a new buff or modification to boost SAM and other jobs like MNK (my job) lol would get nothing. Out of all the jobs SAM would get the most equipment, could wear heavy and light, and would get a variety of good weapons. It just pissed me off so SAM can stay dead! lol That's why I was salty. I hate SAM! lol But whatever it will probably be in storm blood :P
