It's an odd position I chose. Very flimsy defense wise, poor damage (for now), but very good battlefield movement and damage utility. Since I'm usually thinking of things in the 'holy trinity' style or tank/damage/heals I don't know where I fit in yet. Something like a debuffer, I'd guess.
I don't think that has as large of a place in this game as in a traditional MMORPG or even games like FEF. Due to the small player count and large amount of abilities for each player, each person fills two or more very specialized roles.
Ochita: Hindering enemy movement, primarily (we'll start to see more of this as Ochita will be the first to get major terrain-changing abilities). You could class this under "controller" but it doesn't really fill out the rest of the traditional Controller role. She's also a backup healer.
Vilhelmas: All-or-nothing, costly destruction. Even if he traded his mace off for some other weapon, he's going see his first Proficiency skill earlier than anyone else in the game (even Teressa and Inezach), and he'll still have fireballs. This alone elevates him to the team's best melee fighter.
Boothany: I want to call her the "shake things up" role. Doesn't really fit any of the traditional roles because her niche is, essentially, ruining my plans as a GM
Boo Bomb in particular as she learns more of those.
Teressa: Not really a tank but more of a Buff Paladin. Her gimmick is very similar to Vilhelmas, but she's more oriented around boost-then-battle skills than just rushing in and hitting things. Due to the way Zako described her skillsets, she'll be the first to get a Finale ability (I don't remember if we got to any true Finales in the old MKW, and I know that the spinoff game had them but didn't see them used before its death).
Tanky: Probably the most traditional role other than Vilhelmas. Aside from shooting things until they die, he'll be the first after Ochita to get any mod skills (if he chooses).
Inezach: Really a jack of all trades at this point, his shtick as a speedy tactician is ruining the normal enemy tactics that are going to screw you guys over more and more (even in this dungeon).
Of course, the whole point of having every Ability Path give you options every other level is that you have a little leeway in how to build your character even after they're built.
