Cross Class Skills

[Enkidoh]

That's probably because of Sentinel's origins in FFXIV as an actual class and not an ability (yes I know it's a traditional ability that appeared in past FF games, but in FFXIV 1.0 at launch it was actually a special sub-class you got levels in if you equipped a shield for those classes who could). Hence because GLA/PLD use shields and MRD/WAR doesn't: no Sentinel for you. Rampart probably has the same line of thinking (I'm just pulling things out of my head here, so that might not actually be the reason why the development team did this, but it does seem to ring true.)

They need to work on this big time. The amount of cross class skills you can use on your main jobs is pathetic, and oftentimes you have a hard time figuring out what to use, because what there is, is often crap.

I agree they should allow more cross class skills, they can always reduce their potency or increase cooldown to balance things out.

I would just be happier if they didnt cut the slots of the cross class abilities in half when you get the job at lv30, the class has 6 at lv30 and the job 3 so the class gets 8 at lv50 and the job 5. I do understand the job is more powerful for its specialization but still, those 3 slots would be so much more handy
