Another perspective; campaign is the only reliable source of greenies.  The drop rate, if anything, has been nerfed.  have difficulty maintaining a stockpile of greens as it is.  FGS please do not dreduce the rate of greens.  The greens are worth more than the equipment, which averages around 10k, greens drop 2-3 at a time so worth 10-15k per drop.  There is no other way to get them reliably.  Market? Please! I opened 250+ greens yesterday at it was a slow day.

if you need silver or equipment, go to the dungeons.  Camp is for grinding food and greens are a part of that.  Camp is horrible for diver's, go to dungeons for that.

I am talking about a bug that occurred sinch Ultimate DeathKnight have be brought to the game. The chance of getting Mystery
Shards has been increased a lot. Please return it back as it was before. 

I did not ask here in this forum until I made
sure that there is a change in the drop rates of Mystery Shards. I have 1200
Shards only from grinding 12.3. This is too much and useless. 

I want to level up 3 champs at the time. Campaign grinding is better that Dungeons to level up more champs together. I want to get benifit from the Silver while leveling up champoins. What is the use of 1000 Mystery Shard in one month? It would be better if I get only 400 Mysteries and sell 600 shields than keeping 1000 mysteries without need them.

mystery shards give low  players chance to get  rare champions

also there are great to get easy points in events for summon

the should buff it  because it will help players

im lv 84 and still some time i use it to get points in events

There are a few ways to level champs, but if you just level champs in camp, it takes the equivalent of 720 commons to make a single rank 6 champ.  At 400 a month you will never progress.  As mentioned above, it is fairly common to open 2 or even 4k to complete summon/ chase events to get fusion/frag champs.  I opened 5k on my first successful fusion.  There are better ways of getting silver, camp is optimized for food, which requires greens.

I wish the drop rate of Mysteries to be 4 shields against 1 drop of mystery.  Now it is 50% 50%.

My main purpose of farming campaign is to level up three champions at once. I cannot do this with Dungeons. I wish I could get more silver while leveling up instead of wasting my energy to collect hundreds of Mysteries. The drop rate was much better last month. Something have been changed recently. I am talking about the drop rate of masteries that have been changed recently. Please Plarium return it back as it was last month. 

 720 commons = 350 drops of two mysteries a time. I got 1000
drops. The drop rate has been changed last month. Believe me.  

Sorry, I don't believe you for a minute.  ive spent the past 3 days in camp and rates have not changed.  I wish they would drop more greens.

Without getting too much into Mysteries and their utility which has already been covered...They're quite important given the food grind and summoning events.

This is the first time I've heard anything of drop rates in Campaign being suspected of being different than they were before. A one month sample size - even if you kept picture perfect records - doesn't necessarily confirm anything. 

I can ask next time I talk to one of the Community Managers, but I have my doubts anything has changed with Campaign rates. 

Please confirm with them. Thanks

I noticed that the drop rate of Mysteries Shards is too high in single battle. While very low in Multi-Battle.

I noticed if your player name has 2 consecutive vowels, or if you were born in the spring, the drop rate is double.

The developers will receive my observation not you. I have my statistics.

My statistics are just as valid as yours, seeing as they are both nothing more than anecdotal observation.

Alright alright.

I can tell you ahead of time that I've seen nothing else floating around, no complaints or any noise about this change. If the rates had changed we would have almost assuredly heard about it, given the influx of feedback and reports on bugs that spawned from the latest update. 

I'm inclined to believe nothing has changed, but if I hear something to the contrary I'll let you know. 

Many thanks to your usefull reply
