Yes, it has been done in the past. But it happened almost 4 years ago.

The event has similar contents that i added in my suggestions, however.My suggestion contains some other information, the event you provided in the link, it did not have.

However,  My question is, what do you think, of an mini  event that requires  Effort in order to get prizes? i want to see your opinion, your experience and your constructive comments.

So why suggest what you claim is an "original idea"? Its already done, why not ask for a repeat and link to the event?

To be honest, I dislike the event culture where people just login for events. I don't think its healthy for the game. Especially in the current state of the game.

Also, the MDP kind of replaced it, but is being taken out due to stability reasons. Plus, as a further point, we know how slow the site does get in events.

SDE have said that they are concentrating on fixing the game, and to be honest if we want them to really pay attention to this section, we should try and help them with fixing the game rather than dressing up old ideas and trying to take credit for them. 

Maybe way in the future, but I don't think wasting SDE's and the communities time on this is needed. 

I have read the Objective 2015 for the game and yes, the Server stability and fixing issues is an priority, and i couldnt agree more than that. My Idea is not really 100% original, after you posted the link, which is similar somehow, and cannot take credits fully for it, but it has some contents that can make it differently, not really much but definetly will make it a challenge as event, and repeating the event is not such a bad idea, but it needs to give a motivation to players to play hard for example, Non TOP players prizes, that it will required an required amount of event experience to unlock a prize as i stated in my original post.  Events like this can have different names

Example

If this months event name was Operation Red dawn

Next month could it be Operation Genesis.

Which the best player with the highest amount of event experience, gets a trophy. Something similar with NF Crystal. 

As SDE also mentioned, that they also have plans for Daily, weekly, and monthly events. So, i was thinking, having a permament Mini event, where people has to work hard for the prizes and not just a routine, where people just log in for the events as you stated, is not healthy for the game.  Agreed with that. To be honest, my proposal its a way to break down that routine, or at least we could work sometime out, to make events have more challenge and fun at the same time. ( of course, after the priorities gets fixed first ) 

Its not really wasting the time, as there as many complaints regarding drops and exploits. Or people creating multiple accounts just for the drops, or for the bingos and things like that, please feel to add if i am forgetting something else in the list. We can say, we are addressing this issue , to the format can be replaced where thoses issues can be reduced significantly, not to say 'remove' completly for x reasons.  

An event that involves the MDP, then yes. The MDP mostly would be given the best prizes ( uniques ) to thoses who really plays the most, by accumulating most experience points. 

But overall, players would be working hard, to obtain or unlock prizes. Which means, everybody will have the chance to unlock an EBB'ECV if they get the amount of event expeirence enough.

So, what can we expect? players would be contributing and attacking alot, so the more personal attack they inflict on enemy, the more event experience they get.  

So basically you want MDP to return when it causes stability issues. Ok. Rename your thread please.

...and still is utterly pointless.
