Well how much str do you have in your build? you can't expect good auto attacks with 5 strength. Also, what is your wand ability?
I understand the reasons why some mages dont do this but in alot of your posts you state that auto attack is so great. I'm just reminding you that you also have an auto attack button, you just choose not to use it. losing 50 focus for strength wont hurt you that bad and can make a significant difference in your damage and the trident gives a flat damage as well as some strength bonus and has regen.
Mages autos don't suck because mages are bad at them, it is because they don't have any stats to support them.
...having 5 str and doing auto attacks on a mage does not work.
The idea that you only hit for 30 with wand is based on your stats and gear, this is a choice you make not a requirement .
Just to clear something up, unless the weapon you use has a physical component (slash, pierce, or crush damage), strength does not affect the damage dealt with that weapon. Most wands do not have a physical component; they typically only deal magic damage, fire damage, or cold damage. There are a few exceptions, such as the Wand of Hollows, which deals 15 magic damage and 2 crush damage, but all in all telling a mage to add strength to increase wand damage is poor advice.
Also, as far as I know, strength does not increase the damage dealt when using your bare hands. Because mages cannot equip knuckleblades, a mage h2h build is stuck with bare hands. Thus, telling a mage to add strength to increase hand to hand damage is also poor advice.
Please do not take this as my having a stake in the argument over whether or not to use a mage, or whether they should or should not be dps or support. I am simply correcting an apparent misunderstanding with regards to the strength stat and it's usefulness to a mage.
