Int/Dex hybrid class speculation...

Assassin makes the most sense, especially when you figure that it's a Templar game. I mean, can you really have a game with Templar and NOT have assassins? Think about it. Heck, black and white checkered floor tiles were a masonic symbol for the Templar and Assassins in the holy land. Not only are we short a class and the presence of assassins, but Int/Dex is exactly how I would describe them.

Possibly assassin, and it'll be a female class, seeing as we're missing one for balance.

Wish there was choice of gender for all, I like to play tanks too (and I'm female, so would prefer to play as a female no matter what class I play).

Anyway, another female, maybe sin.

Shaman or something similar.

Druid Shape shifter is my bet on what this class might be.

Change into a animal and attack melee range

Human form for spells

It can just as fine be a man as a woman, there is no "balance"

A shapeshift druid sound like a great bit of str to me since it would be a melee form most likely.
I think a ninjalike design would be a best choise for int/dex charackter.
Using poison/throwing weapons/quick melee weapons with skills like bombs / smokesbombs for damage and evasion.

The trick with illusions works with ninja best aswell.

Alchemist/poison crafter. Limited close range melee with a flare for tossed concoctions, augmented by intelligence.

I believe this Int/Dex hybrid will be insane with quick nuke spams and good at kiting as well as close quarters combat will be efficient with enfeeble spells and elemental add to weapons

Yeah, I think an assassin would we cool. It would be similar to duelist, but instead of focusing on physical attacks, it would be more focused on mental warfare like hallucinations, shadows and different types of poison.

Martial artist or assassin, fast melee attacks and debuffs/poisons

hmm i think there's a lack of control in mobs so ill add this why not make a harlequin/jester type of class with fast critical attacks and control spells like bind and stun, that could fit on the int/dex scheme and still be a useful class in party
