You can't have LDoN without having PoP too.
Reason #1: having LDoN without PoP too means you're really trivializing pre-VT raid gear. Most of NToV--which you know was *THE SHIT* in terms of gear when Velious was current--would be a waste of time compared to what you're getting off of LDoN merchants.
Reason #2: Most of the LDoN raids would be unbeatable at level 60, especially without VT gear. They're all capped at 54 players so zerging the shit out of them isn't an option, either. You're not going to be able to tank the namers in this one
http://everquest.allakhazam.com/db/q...tml?quest=3783 for example at level 60 even in full VT.
Reason #3: The prize of the LDoN raids are the augments, which are all either type 3 or type 8. Items with type 3 slots can be purchased from LDoN adventure merchants or dropped from LDoN raid chests, but type 8 slots are only found in plane of time gear (and in later expacs). Meaning most of the augs you're getting from LDoN raids you literally can not use.
Reason #4: All of the high end LDoN merchant stuff is recommended level of 65. All of the raid drops are required level of 65.
If you wanted to do LDoN without having PoP first you'd have to customize it to the point of almost starting from scratch. Implementing the current iteration of LDoN wouldn't work for level 60 characters.
