Let us ponder upon classes, the very thing that defines one's playstyle the most in World of Warcraft. Whether it be the ever-gorgeous, plate-clad warrior who shouts, "I HAZ TWO ROCKET SWORDZ, UR POINT IZ INVALID," the warlock-hating mage or the mage-hating warlock, or even the druid who thinks that Woodstock was really great, we all have our preferences on what we think is the best class of them all.
Yet if Blizzard has taught us anything, it is to plan for upsets or twists in class selection. Remember the great death knight massacre of 2008? Everyone and his great-grandmother's mailman had a death knight. They were easy to acquire, incredibly powerful and just a blast to play. Yet modern death knights are shells of what they once were. They play like the polar opposite of paladins now, but upon their initial release, they felt more like a battle mage class. Now, thanks to a complete revamp of the death knight class, the closest thing to a battle mage is long gone, leaving those who enjoyed the class idea from different roleplaying games feeling rather empty and disappointed, much the same way as when we discovered that the delicious cake we were promised was actually a lie.
It leaves us with a curious idea, though. Considering that the idea of a battle mage in WoW is doable, could it be brought in as its own class? Or would Blizzard dare to put in a totally different class?
I personally would love the idea of a monk class being brought into WoW. A class that specializes in staffs, polearms, fist weapons or just good ol' fashioned, unarmed, beat-down-style fighting would be a blast. Maybe even have a healing class that uses chants (much like a priest) but has a completely different resource known as meditative power as its ability fuel. They could switch into different trances to gain certain abilities, much how a hunter's aspects work.
If you could have any new class (whether it be from a roleplaying game of old or maybe a class you enjoyed from another MMO), what would it be? How would the class work? How would the class fit in lore-wise?
