I don´t like that battle system for an RPG, at all.

That is not hack'n'slash gameplay.

Its got a system with a lot of depth judging from all the previews I've read. I'm moving all I've seen so far!!

After playing FF12 and Kingdom hearts, this was literally the finally fantasy I have always dreamed of since then.

Great. Let's slice and dice Dragons in button-mashia land.

Final Fantasy has the problem between turn based battles or real time action: if you make an action RPG the loyalist of the series will complain of the changes done to the series, but in this day an age, you can't make a turn based RPG (with all the expenses of the engines, marketing and multiplatform developement), sell it for 60€ and expet people not to complain. It's a lose-lose situation.

Its as much a rpg , the witcher 3 is not a rpg ?

What's FF signature battle system ? you mean the turn based from 1-2-3,  simple atb from 4-6, job system from 5, atb with a twist from 7-8-9, turn based from x, real time move system from xii or weird atb from XIII ?

FF signature is to reinvent itself with every game.

This 15 is the first FF that I wont buy. I dont like H&S games, i want my FF games to be turnbased .
Hope FF 16 will return back to basics.

Well DEFINITLY look like a hack and slash game (Which is GOOD!) with its High speed combat mode when you activate the ability bar!! At 01:02:25 on this video

They better add enemies with ranged attacks otherwise I don't see why I shouldn't spend the entire battle warping up and down.
