Playing pvp and using common sense as well as just observing and studying the other classes. We don't live in the age where you have to actually do the research to become knowledgeable about the situation. I have played pvp, seen the classes, saw their build tree, and that is what my argument is based off of. Just because you got offended because you main Titan doesn't mean I am wrong, letting your emotions fuel your arguments makes you just look ignorant.
