you may aswell not play till 4.0 max level raises to 70 and then youll be right there were everyone else will be without any effort put in. your old gear wont help you nor will you need it at all since even quests hand out better stuff. unlike a non cap raise expansion were your old gear may not be the best anymore aswell but itll HELP you by making the new endgame content a bit easier to handle for example.

With the exception of XI, which released expansions for 7 years without raising the level cap, that describes every MMO expansion.

Anyway, they know the lack of new systems in HW is an issue, they said as much during the anniversary stream. It's why they're diverting resources from patch dungeons to developing them. Should they have been in at launch? Absolutely, but I have no idea how much that would've delayed release.
