Not being diplomatic, I'll just be blunt.
Eloraam worked hard for about 7 months after 1.3 caused some MAJOR problems within RP2 right down to the deepest levels of the mod. Lest it be ignored and glossed over, she publicly stated a boost of donations allowed her to take some UNPAID LEAVE from her job to finish up RP2 a couple days before CHRISTMAS. Not only has Elo delivered a wonderfully deep and useful mod with widely varying flavors of complexity, she pulled off things like an implementation of FORTH, the mighty frames that move blocks en masse, and a multitude of other wildly complex things few members of the community are even scratching the true surface of for all the potential. Of all the mods out there, RP2 has in many ways reached the farthest, shot the highest, with likely one of the BEST records for reasonably stable releases. Also don't forget 1.5 is going to likely require a rather ludicrous amount of work because of fundamental changes that Minecraft will undergo and it WILL affect ALL mods in some way. I'm just hoping Elo does not have to endure a year of work just to get the current version functioning to her excellent standards. Take a minute and consider every block, item, and tool in RP2 took hours, days, even perhaps months each of dedicated effort pulled out of spare time. And all of it out of passion alone.
If Elo felt done with RP2 (and there is still a LOT of things yet hinted towards), it wouldn't be terrible and the community would deal with it and find other ways of playing. It is a great mod to have but not the only option. Perhaps Elo had work issues keeping her occupied of late and a hobby had to take a back seat. Maybe, gods forbid, a family emergency or health problem. I don't care even if it was a very well deserved vacation from Minecraft and modding to recharge. Nobody has any right whatsoever to claim Elo owes them something if for no other reason than all the quality goodies and fun we've all had using RP2 thus far. It's her personal project and she knows people love the mod but we the fans cannot expect anything more than what she feels is right for her work. It's a work of art she shares by choice with the world. She could keep all the fun to herself and nobody could do jack, nor would anyone have any right to. Instead, she's helped so many of us have tons of fun.
Reclusive or not, Eloraam deserves mountains of respect. Don't like her not meeting your childish demands for immediate action and details, stop using Red Power 2 and shut your bloody hole. No mod dev works for you.
