Not a notorious poster, just the average player whose strength here has been drifting the last few months so here i go :S
Ill start by saying IMO what makes something addictive is when its a challenge and you feel like you have to keep doing it until you get it right, so for future inclusions think about that,'will someone wanna keep doing this repeditively' you dont want your great new thing turning out to be scavenging all over again, but HERE...
-A few ideas first-
Im not a PVPer, i see all the previous posters who seem so PVP inclined roll their eyes, but i think something like the first strike enhancement to give you a chance instead of always a 9/10 chance of teleporting away from your mobs whilst hunting if your spotted would be swell.
Also on PVP if they love it so much let em have it, how about once a week, fortnight or month somewhat random in timing there is a solar phenomena and all areas become PVP enabled for 24 hrs, iuno.
Maybe each crystal medal you achieve you get a +1 energy gain to recognise your efforts and wanna bother getting the medals all the way to crystal may help the medal system.
Maybe medals that are faction specific, eg richest faction for x amount of days and then the faction gains a +1 energy gain or something of the like.
-Good ideas i read-
Obviously a new behemoth or new blueprints for the existing behemoth or both is gonna happen regardless, should be nice
Other uses for AP also good.
Some sets with energy/xp gain was a brilliant idea maybe even elite hunter too.
Blueprints being sortable is a must, its sending me
I think the higher/lower level trading is brilliant, a lot of entities drops could become reusable in inventing things later on in some blueprints, what blueprints well... but this may help to encourage an economy.
Arena would be nice, but im sure thats a lot of work.
RD was right, 2k for that little increase in stats is a ridiculous jump, maybe the next level up could be 2k especially as where i am i still see no increase in credit drops, by the way RD i seem to remember being the richest faction for a few months, eat it
-In closing-
Keep listening to the posters if this is ringing true
Lengendary events usually cheer up the majority and I hope your mecha idea is all you hope for, sorry i dont have brainbending ideas, just a few ideas and comments that would make the game easier to contend with till the cavalry arrives
Thank you very much, Undjuvion is almost outta the building

*but trys to wait patiently*
