The Warriors are the most powerful among the other classes the mages & rogues.
The Warriors can take more punishment from enemies then the other classes, That's what am going to explain.
The attributes for the warriors are Strength and Constitution, As you know strength increases the attack for warriors only & Guard damage bonus to all classes.
Constitution increases melee defense & health points to all classes.
So if the warriors are strongest, Then they don't Health points like the other weaker classes.
So this must be fixed, Constitution increases melee defense & ATTACK, Not willpower which increases magic defense & ATTACK.
The attack goes to the warriors, Not the mages.
Dexterity & Cunning are for rogues specifically.
Who is better to control the battles?
Not the rogues of course, If a mage involved heavily on a battle, Then they'll attract attentions which makes them in dangers.
The warrior should control the battles, Attract all the threat, They might not do damage like the rogues then the mages, But they are the best class to control the battles.
Attacks increases all damage, Horn of Valor for example, From warriors, Will increases all the damage dealt for a short time, Not to mention Taunted enemies will be more vulnerable to damage.
I think BioWare should fix their numbers, Or maybe they want it that way for some purposes,Like grinding the mages on DA Inquisition Multiplayer?
