it depends. if you like Zynga style gameplay, but think you should be paying a monthly subscription for it, then sure. jump right in. if, on the other hand, you are a proper gamer, and you are looking for good challenging gameplay, dont touch it with the proverbial barge-pole.
everything outside proper raiding requires no skill or intelligence. proper raiding requires you to organise your life around the game to some degree. if that sounds attractive to you, then feel free to get involved. but imo, you are 3 or 4 years late to really enjoy it.
