Allow me to start this with saying I have only ever played a rogue. For at least 8 years only one character. I love playing a rogue but am thinking of playing a shaman. My concern is I have become so used to the rogue play style and little perks that it will hinder me from effectively playing other classes. I am used to my stealth and vanish and being able to go wherever I want no problem. For PvE and PvP. Also I am worried about having to redo achievements. I know they are account wide and all but I am one of those where I want to achieve it legitimately on my new character.
Also I have tried alts before, but when I have an alt I tend to ignore my main almost completely.
If anyone has any advice or experience with similar situations feel free to post.
