And currently elite has 4x the reward for ingredients vs normal and 4x or higher drop chance. In the case of mythics it's 10x higher drop rates compared to EH. I suspect the same for jibber's blade because I've never seen it drop below EE.
Elite already is a much higher reward and that doesn't even count bravery bonus, saga rewards and favor which also are much better rewards on elite.
Even if Turbine increases the elite rewards it won't be enough - people will always be whining for moar moar moar. Other games have very diminishing returns for the most difficult content for good reason - to keep people focused on the hunt and not whining for moar and better stuff because they are done. Turbine needs to add more things like jibbers blade but make them even harder to get like eross. They should never add a really rare unbalanced item like esos again that was so overpowered when the level cap was 20 that it trivialized boss fights.
Why do you keep comparing medical school to ddo lol. That is the most ridiculous thing I've ever heard.
