So this is an interesting one. You can now get all classes to lvl.35 on a trial account character and unlock all the pre heavensward jobs and the first couple of quests in each jobs storyline.
So now for free you can get up to Titan, dungeons like Haukke Manor and try the jobs, the betters sets of abilities and you get a way better experience. God knows the amount of times i've heard people say it 'seems slow' because some classes like lancer have little off gdc skills by lvl.20 at the current cap.
So now the free trial as of next patch day is
>lvl.1-35 on all combat and crafting classes
>ifrit and titan primal fights
>satasha, tam-tara deepcroft, copperbell mines, halatali, thousand maws of totorak, brayflox longstop, haukke manor and sunken temple of quarn dungeons
>all but the last 2 guildhests
>hall of the novice
>all pre heavensward jobs including Ninja that came in ARR patches
>golden saucer
>chocobo racing
>lords of verminion
>triple triad
>story up to the beginning of the empire/ultima weapon arc
and theres talk of a lvl.60 character for pvp as well.
