Well what do you expect?
Its a 13-in-a-dozen korean P2W grindcore game
Honestly even not the worst of it's kind and i did somewhat enjoy the strategy involved picking the right abilities at the right time etc
These games are meant to be fun for whales dumping their cash so they can pwn other players and storm leaderboard while increasing their e-pen!s
It's certainly not the worst way to earn some SG, and although it slightly amused me at times, as soon i did the task i cashed my SG and never turned back
I enjoyed it enough to be able to finish the task, unlike e.g. World of Tanks, i HATE that game and will never get any SG for trying that one, or Final Fantasy which takes DAYS of grinding and has an extremely high deny rate
Remember the game publisher is looking for whales(ppl who spend lots of cash) and so pays advertisers (GameHag) to get new users(you) to signup and get addicted so they will spend money
From the money for your signup(and according task e.g. reach lvl X) you get payed in the form of SG (after GameHag takes their piece of the cake of course ;) )
Get used to these type of games if you want to earn anything by playing games on GameHag, because they are basically all use the same monetizing structure
there is no such thing as a free lunch
