This does not play like WoW, other than you level and complete quest. It is real time combat not the point and click that WoW does. While this game is seriously lacking in many areas, and they grind the pay system into your face with a pay to win model, it is not the same as WoW. The only real  similarities is: Fantasy setting (sword and sorcery), RPG class based system, crafting system (which is different that WoW), and you fight through dungeons. If that is all it takes to be a WoW clone, that makes almost every game out a WoW clone. That would make "Elder Scrolls V: Skyrim" a WoW clone. I am not a huge fan of this game, but saying this is a copy of WoW is just....

Dracula is a Belmont, but if you remeber Castlevania III Trevor frees Alucard to help him fight Dracula. So it could not be him. Also in SotN I belive you fight a zombie Trevor as Alucard. I am a bit hazy on SotN I did not play that one as in depth as Castlevania 3.
