I'm sorry Vulcan, but I'm pretty sure you're the one who got lost in my comments.
I'm sorry that I'm a literate person and I need to use complete thoughts and sentences.
On the way to school I was talking to my 15 year old brother and he even understood what I was saying and trying to explain with the percentages.
It's ok though Vulcan, just because you think that I don't know my own class, i.e. telling me to go look at their skill costs.
I know my skill costs, and increased them to that of a Caster class for example purposes.
Because they are so low, you don't see Melee users using a lot of MP, but that's not the point, what Melee user would need to use magic, except to empower the weapon with magical properties, which in reckoning sense would require less Mana than to completely and utterly form something from thin air, i.e. a Shockwave or a Fireball.
You're thinking of it all as a this class must = this class, not in the literally sense.
Cloth doesn't need to tank, it can't tank because they wear clothing. And last time I checked, clothing was easily sliced through with any form of sharp object.
Mail is harder to slice through because it is links of chain woven together, but someone with Magical properties or a giant ass sword can easily cut through mail armor.
Heavy Armor is harder to move around in, but offers great protection against full on brute force attacks, but is easily heated up or twisted or something with magic, and any skilled assassin can place a well thought out knife between the cracks.
Each class has their weaknesses and strengths, just because your strength is high burst damage, and your weakness is high MP costs doesn't mean you're worse than the next class, or a sitting duck...
It just means you didn't think through your skills and consequences well enough.
Using the same sentence you had in your original comment, only twisted.
"If a Mage MP go down so fast meaning hes facerolling his keyboard or hes just suck lol."
c;
I do know what I'm talking about. Maybe you should just stop reading the first couple sentences and trying to base an argument off that.
