any fighting class character worth his salt will use a weapon you don't know anyway, meaning your parrying will be very poor even if you have it at 100%.

Mages are not about parry, dodge, and shield block really. They are more about avoiding being targeted or reducing the damage through spells.

You blame -something- for all of your problems. Look for a solution within the current framework. Since you were playing a conjie recently...

Gear for hp. Use reduce and enlarge potions to avoid being lagged. Avoid axe and mace specs. Don't spam. Now, when you get engaged by an enemy, you should be able to flee as soon as your servitors get involved, and after that you don't have to tank in most cases.

Also, you don't need to gear for damage like a warrior. You can gear for hp. You can use magic to haste yourself more easily than a warrior and protect yourself more easily with magical sources, since you can use them all whilst a warrior is restricted to potions.

At lvl 30 you haven't reached the peak of your power yet, and mages to tend to be on the defensive until upper ranks (though conjurers are different). Maybe you need to be attacking your enemies while they are already fighting something else, so a mob tanks for you.
