I do hope they add a new class or two. Those are always fun.
I have been playing with ideas for new items that they could and/or should make. The coolest one was more of an impossible happening and more of just a cool thing to think about, not to mention a programming nightmare and a big trouble with copyright infringement.
It would be a set of AF-esque armor called MJOLNIR (yes, the stuff that Master Cheif wears). The plain 5 peice armor set would be nice, with nice stat boosters and DEF and the "back" peice would simply be the black undersuit worn under the MJOLNIR, and it would just have a bunch of +'s to elemental resistances.
The cool stuff would be in the weapons, belt, and earring (can't really think of a ring yet). The weapons would be, of course, the human guns in Halo. You'd have the Pistol with mid-damage and mid-delay. You'd have the Shotgun with high-damage and mid-delay but a - to accuracy. You'd have the Sniper Rifle with a high-damage and a very-high-delay, but a + to accuracy. You could also do the Assault Rifle, but you'd have to make the "Ranged Attack" button able to be held down for the automatic fire and for every 5 rounds or so you'd have to - 1 to accuracy to take recoil into account. These guns would be available to only RNG and the bullets would be dirt cheap.
The belt would be for NIN. I imagined the belt holding the shield that Master Cheif uses in Halo. It would give the NIN a free usage of Utsusemi every 3:00 or something and would get shorter as the NIN levelled more. The idea behind both the weapons and the belt being that they give the NIN and RNG rewards after having gone through so many levels paying for expensive scrolls and arrows and bows.
The earring would also be cool, but it would focus on helping mages. It would simply be "Cortana" and it would give a bonus to MND and INT.
As I said, this will absolutely never happen, but it is fun to think about. Back to your regularly scheduled thread.
