Elysium, I'm sorry you don't understand how the patcher works. It's unfortunate that you're presenting speculation as fact. The least you could do is test it, which I suggest you do, for your own sake.
Up until sometime last year, whenever a file was updated, the patcher downloaded it completely. Now the patcher uses something called a delta file which is the difference between your version of the file and the updated file. In this way, bandwidth costs are cut. However, processing power is a lot more expensive than internet bandwidth, so rather than generating a new delta file every time someone patches to figure out the difference between your version of the file and the updated version, the patcher has delta files for each recent generation of updates. These delta files only go back as far as the delta file system was implemented, which just happens to be later than the data on all EQ Trilogy releases.
In the end, installing off of the EQ Trilogy cd's will save at most ~500 mb of downloads. EverQuest patched up to LDoN is around 3.9 gb. There is not way more bandwidth saved by installing off of cd's.
As for what Sony intends you to do with their patcher, who do you think you are to preach? You updated your client just like everyone else to play here. You did it from their servers using their bandwidth. You're either bitter because you look like an idiot for claiming my link was a virus, or you're trying to conform with the administration here who remember a time when passing out information on getting the client was dangerous. Either way, get over it.
