Moving will be made to interrupt spellcasting at a point in time...

I would say you have a point however... there are no instant cast spells if you look down the list...

While it's true that CNJs don't seem to be getting any instant casts in their grimoire, according to the Class Reforms Action List, it seems that WHM will.

WHM Abl. 1 - Eliminates cast time of next spell.
WHM Abl. 2 - Instantly restores HP of all party members.

I could see these abilities allowing instant cast spells that could be used while moving. And while it hasn't been mentioned that this is Yoshi-P's plan, anything could happen between now and 1.21 when the Jobs go live.

Also I played WoW for a long long time (along with so many other MMOs it would take too much space to list here) WoW is not something I would call twitch game play hehe... the combat was never really fast pace and most of it came down to spell rotations and such. Yes yes there are a number of boss fights you had to move here really fast or do this and that but really it is not a twitch MMO.

A real twitch MMO would be something like oh... Tera or maybe GW2... twitch game play is akin to FPS games and really WoW is not even close to that.

I haven't played the games you've mentioned, but out of the MMOs I have played, WoW's combat is the fastest paced. Especially PvP, it all comes down to instant abilities, positioning, line of sight, etc. So, I'll give you that, there are probably other games that are purely twitch. But FFXIV is still not what I consider to be fast-paced combat, even if it is faster than FFXI.
