Man I hope SAM can move when chargin/using there special move or moving cancels the action and not lock you in place.
If not then SAM will be the defacto floor tank (it will be a fusion of jumps and leylines. boss will mark you with an aoe).
Heck even if you can move, but cancel it I can see most SAM not budging
While it's possible they'd go with such a terrible idea, it's unlikely. There's nothing really indicating that's the case either I believe? I mean the video shows the samurai standing still, but so did every video showcasing a class because the animations when you're moving look wonky quite often. You might have a charge system that lets you charge up while moving though.
Stuff looks great to me, but I wasn't expecting more or different stuff anyway. I was already assuming it was gonna be SAM and if it was that it'd be a DPS, it just makes more sense to add DPS classes when most people play DPS anyway. Heavensward had faster dungeon queues while leveling but that only lasted like 2weeks and was only relevant until cap at which point queues were normal again, cause it turns out DPS players for the most part want to play DPS classes, not tanks/healers. I believe role distribution is pretty much the same as 2.0 even after adding 1tank and 1healer. And if they want to speed up leveling, all they have to do is make the 50-60 dungeons worth doing when lvling to 70(in Heavensward they gave no xp for a long time so running the 50queue was terrible and the 1-49 was meh too). Well that and you can just PotD anyway.
I knew the gameplay stuff wasn't going to be shown or only as a small teaser, not cause they said so but because that's what they did with Heavensward too, they revealed the classes but the older classes new skills/new LBs and whatever else came later in like april or may during one of the live letters, it was a pretty long one too and they showed a lot of stuff like different flying mounts, concept art for AF2, some actual gameplay and stuff like that.
The focus on Doma and the far east is a bit surprising, but makes sense if they felt Ala Mhigo was going to be too boring visually(and honestly, don't need a 2nd Thanalan). And fits with the class obviously. And lore wise it makes sense to go fix the stuff there too before the inevitable war with the Garleans.
