I feel like such a nub ( i am actually, first time playing any FF game ) Do we gain ability points every level? if so.. i'm level 30 and have not spent a single point lol!
Relax! And welcome to the game and these forums, friend!
If you look over your character menu screen, you'll see along side where it says Attributes there is a + symbol followed by the word bonus, and a numerical digit. If you click on the + you can put said points to your attribute totals. Each class/job is different, so you don't have to worry about it being a set thing for each class, just the class/job you are currently on.
Attribute point wise I've been doing for 3 VIT put 1 into STR. Which I feel works quite nicely though I would be interested to see what others have been doing.
I currently cross class Provoke, Flash, Second Wind and Feather foot these are quite useful for tanking I find not sure which I will add 50 maybe the Crit hit one from PUG to improve damage to help grind down bosses a little bit.
I think most agree, if not overly allocate points into VIT. I've done the opposite! I've put mostly into STR only because I feel the benefit into STR for a tank maybe better than just HP which VIT only offers. It's not like it is helping me take damage less, just have more HP to take more damage.. which from a healer standpoint maybe not necessary given the increase to blocking/parry STR provides. Not to mention the damage done tacked on helps in it's own way. I'm not a math guy, so I can't say that one is overly better than the other at this point. Given the lack of data so far, perhaps no one is saying until more testing can be done end game? Either way, we can always change this if needed on our characters... so right now it's go with what you think is best.
In regards to additional ability from other classes, I've not really put much extra enmity abilities up other than Flash. I actually feel what I have get's the job done, with flash, and overpower.. tomahawk on pulls, and our single target moves of skull sunder and butcher's block.. not to leave out our stance of defiance. My cycle has been (at level 37) pulling a single target with tomahawk (after marking mobs before pull mind you) and gather them with a flash, and all together in front with a overpower. Enmity is set on all at this point, and I can work on my marked number 1 target.
Healer can pull aggro on the others during this so I'll lay down another overpower in between a combo cycle of heavy swing/ skull sunder and butcher's block. If aggro is made to anyone else.. Flash them up and lay down an overpower again. Then I just go back to my combo routine. If I can manage it, I'll throw up the fracture and work in a maim or a bit of better DPS.. not a priority of course. Naturally, I work around mobs that are casters, have particularly bad AoE moves and patrols that wander in. It goes without saying that running dungeons over and over helps learn the layout.
Food.. not used too much, but I know I need to eventually, as well as materia.. but not a crafter at this point, I have nothing to offer myself, and hate to pay a large amount for something that will be gone in 5 levels. At 50, or even 45.. yes, it'll be included. I haven't had an issue yet not having them.
