Ragnarok Online 2 Tank Class Skills Analysis

Alright so I’ve been doing a bit of research for a friend of mine that I’ve known and played MMOs with for a LONG time. He was planning on making a tank of some sort in OBT, and asked me to look into the different nuances of the tank classes and do a bit of theorycrafting for him (mostly because the large part of the joy I get out of MMOs is just that, making charts, spreadsheets etc to maximize DPS, threat generation, healing efficiency, boss strats, that sort of thing). I’ll start with initial information that can be gathered simply from the RO2 skill simulator.
