Definitely me, I am still following the game and come to the forums daily and try to login once a week or so to catch up with the few that are online.
I actually probably prompted this post, as a few hours before he posted here, he responded to some of my skype questions about Eldevin.
I would 100% come back and be one of its biggest supporters if this game had updates both in content and improvements. I feel at the moment though that I have finished (which is an odd word for this sort of game) as much as I can here, and my time can be better spent elsewhere. Dont get me wrong, I did countless hours of grinding here, and I do not mind that one bit, but I dont really have anything to even grind for any more (only TA kills but was getting about 10 a day last time I tried as no one went there anymore). So right now, I spend my gaming time elsewhere, but I would most certainly come back again if there was more to do.
I know with the small dev team, when there was a dev team for Eldevin, updates can and do take a while. Now with even less people that time is going to increase even more.
There have been many great ideas to implement that would drastically increase the longevity of the game, from better rewards/drops, rarer rewards/drops, unique drops, custom craftables, more PvP maps, more PvP modes, bring back group queue pvp, expand the guild system to include guildhouse, GvG, guild emblems and gear, and even your own level 50 and also completing the ascended dungeons. Quite a lot more can be added to that list too, thats just off the top of my head.
How about to drive some development hours and get the lvl 50 content out (and maybe more depending on how much is raised) you guys run another "founder" pack scheme, call it something else, and have different rewards, but something similar. Could even run it through kickstarter or something like that, so those investing could see what each goal would get us. To get you guys rolling and releasing content again thats one thing I could think of.
But please, dont do that if it will just go back to how it is now afterwards. Like others have said, this game didnt get the following it deserved for a few reasons, one being a lack of timely updates. If we have a couple of people to stick around to release small upgrades (new weapons, mobs, minor quests) that doesn't require huge updates (world maps etc). Perhaps even let users design things if there is a way you can incorporate user design into the game.
Anyway, TLDR - I would 100% be back if this game was active in the devs eyes
