They can't drop DoE even if they want - unless the developers do something really terminal, as allot of players and have purchased Moon Coins - real money spent - then the Moon operators would have to offer full refund of all monies and it would be a complete nightmare to implement.
Further more DoE has got legs - its a fairly new game and once it gets going (like KnightFight KF) should have years to run - especially if the developers keep up updates and exciting new content.
I think you will possibly loose interest much more likely than Moon or DoE dropping it.
OK DoE and others don't have massive animations and moving maps like "Lord of the rings" etc - however in my case where data speeds are slow - it is great, likewise when (they may already
) make a mobile version for players who use mobile phones - due to low bandwidth required for this game it will also be great
Of course I could be speaking absolute rubbish I am sure I will be corrected if I am
however I wouldn't worry to much - keep in mind Moon ID took on KF 10 - and I have played this game since Server 2 UK - I personally think this game needs a huge revamp to get its legs back - if it got dropped then you may be justified in thinking On Day DoE may possibly get dropped - in the mean time...
KEEP PLAYING DoE ... Oh yeah tell everyone else how good it is also - the more the merrier
