Classes Developed Backward in MP?

Hello everyone;

In Multiplayer Mode, were the classes developed backward by accident?  Let me explain.

I started by playing Multiplayer as ranged characters; hunter and archer.  I did fairly well with hunter but not much play time with archer, I played some perilous even with hunter and held my own.  Then I went to Duelist when it came out and I quickly moved through to threatening and perilous.  Shortly after I moved to Arcane Warrior which I promoted 10 times, playing only threatening and perilous without issue.  I figured now I would move to warrior classes to get my constitution up a bit.

I selected Katari class as the stats showed MUCH higher HP, better def, and EXTREMELY high damage; along with my unique maul, unique level 6 armor and all the upgrades I put on them this would be my new favorite class.  I am now level 18 with the Katari and have completed a few perilous missions.  What have I found?  I think the devs have built the classes backward in Multiplayer.  Since all of my experiences have been the same with Perilous and the Katari, I will just use my last experience as reference.

Here are the important stats to remember for this:

Class: Katari

Armor: 114

HP: 1,403

Class: Archer

Armor: 67

HP: 1,600

I was the Katari, the Archer was a random player.  As a Katari, I would head in and generate a full guard.  I would continue attacking enemies until suddenly I get melee attacked with one standard sword swipe from a standard little Templar garbage enemy and one archer hits me once.  Suddenly my guard is immediately gone and health drops to 5% max. Full guard and full health gone with two hits; two to three hits and I'm dead every time.

So we ended up getting to Stage 5 of 5 in Feraldine Castle, or whatever the stage with the dragon is called, we faced the regular enemies, NOT the dragon.  Being so open, there isn't much area to hide so I ended up going through both my pots, a few guards and finally dying within about 60 seconds, each hit taking either a full guard or all my HP.  I ended up spectating the entire time, watching this archer standing in the middle of the map, literally getting rocked continuously by 8 of those spirit enemies, the boss, a bunch of archers, and a number of melee attackers all at once.  His health just stayed there, didn't go down much at all; two to three minutes in, he's still soloing it, still taking shots to the face non-stop and taking no damage.

So, Katari, a class that falls under the Warrior designation and in campaign mode is one heck of a tank, gets hit twice and dies.  Yet an archer, the ranged classification, can sit there with half the armor value and take 30 enemies on at one time in perilous mode and take virtually no damage.  How is this possible?  What is going on?  How can the largest, beefiest, most muscular and scary guy in the game being the squishiest...and to that extent?  Katari is supposed to be a high damage slow attack speed melee DPS character that can serve as makeshift tank when needed.  An archer is supposed to be an extreme damage, extreme DPS, quick strike, super squishy ranged character that the tank needs to protect so Archer can provide DPS for the group.

This is completely backwards.  Is it meant to be this way for some stupid reason or is it a mistake or maybe an algorithm issue?  There do seem to be quite a lot of issues with the game's calculations.
