i'm going to boycott the dungeon since it's ridiculous to spend 8 sot for such miserable droprate. in 50 rounds one rare soul and 2* colored shards...so WTF???
as eagle mentioned, sparon stated, that enough people still play the dungeon, but i bet my corrupt general, that many people will stop playing dungeons as soon as they realize how bad the deal is.
so the only thing we can do is to refuse playing the dungeon. for me it's an easy task because i have plenty of 3* shards of any colour. i would only play it if i desperatly need some colored 3* shards...in any other case i would stay away from it...
edit: maybe i will play some rounds to proove how bad the droprate is...
