<Well today I deleted my character and created a new one, a Dps.>
This isn’t WoW. Your character is can be every single class already, with no consequences outside having to grind a tad of xp to catch up. The MSQ progress you just lost (which is the true roadblock for new content) is absolutely painful.
That alone is going to bias most responses against you, because it’s indicative of you not knowing really basic gameplay ideas. In retrospect, it might not be a bad thing you’re making a new character, because you DESPERATELY need to read every single guide/tip they shove in your face if you’re this oblivious.
