You were specifically talking about raid loot. As far as i know, these don't yet have mythic versions, just the one. They already have higher drop rates on elite. We're not talking about getting a slightly better version of the item on elite, we're talking about getting the item in any form, at all.
Believe it or not, there are many people playing this game that can never reasonably expect to beat MOD on epic elite. Certainly not often enough to farm it. Are you willing to pay 5000 tp for new packs to make up for all the lost sales from people who don't buy it because they know there is literally no chance to ever get the loot from it?
I will assume then that you think an appropriate droprate for phlogs in thunderholme would be 0% on epic normal, 2% on hard, and 100% on elite?
Before you say that people who can't complete epic elite raids aren't trying hard enough, i'll just say that the belief that anybody can do anything with enough effort is inaccurate. Innate talent is a real thing. If Shaq couldn't make his free throws, i guess he just wasn't trying hard enough right?
