I have seen heated discussions on this three days in a row on world chat. Some people say because it gives raid gear it has to be level cap only, which makes no sense because there are lower level raids. Some people quote Orion as having said level 140 only - which is more persuasive because one would think Orion would know.
On the other hand - the new zones are low level, and nothing in the marketplace description says that delving is only available at level cap. Nothing in the one page summary that Cord posted a link to said it was for level cap only. Players with low level characters, either on "live" or on the legendary servers which will not hit level cap for a long time, are paying money for the expansion assuming that they will be able to use the much touted delving system.
Can we get a clarification, please? If the system is for level cap only, the advertising should say so. If the piece of it that gives raid-quality gear is for level cap only, the advertising should say so.
Obviously if nothing in the delving system is limited to level cap the advertising is accurate now.
