Will People still use the classes within the prime fights?

[Tonkra]

what i was questioning myself..
the new jobs will only be able to equip skills from two defined specific classes (for BLM it is pug and archer)


Will people switch to the jobs within these primal fights?

Because they are unable to equip for example "Sentinel" which is by many people called a "must" in these fights. BLM wont have more defense or HP than THM nor any of the jobs will have an overpowered "protection skill" for the group. so the BLM will knocked out after the special attack from each primal without sentinel?

i think so or so its a pitty that you need one skill of a class as a must to be alive after an attack.
they need to reduce the effect of sentinel havely and on the other side reduce a bit of the special attack damage from the primes. otherwise i see bad times for the new jobs.

correct me if i'm wrong. hum. its just theory
