Recently, I decided to make my Priest my main. And my WoW OCD dictates that my main be my character with most achievements/mounts/ stupid stuff that doesn't really matter. So I was just curious, even when I was running Outland heroics with my warrior, he took a beating on more than one occasion, so I'm not even sure that Priests can solo old content.
So, in a sentence, should I just resign myself to the fact that I probably won't be able to solo the old content, or is there tips/tricks that anyone can enlighten me with?
