Rogue is also one of the classes that comes up for a close candidate to being a Blademaster. But the whole theme, cheap tricks, not honorable is working against them. Attitudewise they are to different. If we have to put a exisiting class label on the Blademaster, Monk, Warrior and Rogue are the firsts who come to mind. Still they all are very different.
Blizz is on and off with class fantasy and I dont see the Blademaster work with the Rogue. But thats just me. It could very well work for Blizz if they see that in a different way. If a 4th spec has to go somewhere I would put it to the Monk.
But because none of the existing classes really fit the blademaster theme, thats why I think it should/could work as a new class

It is also very weird that we dont see him. Blizz did not forget about him, since he is in HotS. And they did not want to make a npc that just stands around for him. OR we would have one in OG. They also decided actively against making the WArrior Trainer in OG and make that Samuro. Instead they created a totally new one (I think it is Wanakada)

I dont know why people think warrior is the closest. Alone the point that every race can be a Warrior stops this. Blizz would have to make it an exclusive in some way to give this to a Warrior as a 4th spec. Besides that I think a Gladiator spec would fit much more better to the warrior as a 4th spec

Well, you have to look at the toolkit, the theme, the gear. All this separates a Blademaster from an Arms Warrior.
Samuro in Hots is a great template, and he plays very differently compared to a an Arms Warrior.
You would have to work Windwalk into it, Mirror Images, mechanics for dodge, the fire theme for the Burning Blade and a crit mechanic. (just taking stuff from HotS here) Even the Bladestorm has (or could have) a different animation.

who says Blizz wont introduce a new range class? I speculate that the tinker will be the next class, and will have a range spec.
Also 4th specs could help with that problem for many classes.

What are your ideas about a range class?
I see some 4th spec ideas, like Necromancer for DK, a physical range spec for monk, a mid range spec for rogue. Necromancer could become a whole 2 spec class, possible with a dark healer kind of spec.
In the last years the number of ideas for range specs and therefore hero classes was, at least to me, quite low. Havent seen many that could really work without a massiv overhaul of the class system
