I was logged in at Shattrath at the Scryer Bank doing some stuff. So I see what seem like a Protection Paladin right next to me standing there. This his Armory profile. So just being curious I was checking his gear to see how he was coming along as a Protec Paladin. After looking at his gear I kindly asked him if I can ask him a few questions. So we chat for 5-10 mins about Protection Paladin, gear and Talent points.
Asked him a few questions as to how long he's been a Protection Paladin and why he had certain enchants and why he had some points the way he did. Said he was protection spec since lvl 1 and that he was spec the way he was to tank for players in epic gear. I kindly offered him some pointers that would of greatly help him improve his gear and use of talents and even tried to refer him to the Maintankadin Forums for Protec Paladins to aid him. What became obvious was that this player said his gear was all fine and that he didn't need any of my help. Hey that's fine. Wished him well and that was that.
I like to think some people are smart enough that they can listen to someone that plays their class that may be able to offer them advice and make a informed decision based on the advice they may get. I've asked and gotten advice from others much better at my class spec, but I never took it as an offense to clearly improve my gear and spec. A few good Paladins helped me along the way, because I was willing and open to listen to their advice. Clearly there are some people that will refuse your advice no matter how much you try to assist them. Some people will take any advice you may offer them as an offense in how they spec their gear or talents.
