This season’s special sponsor achievement is one of the most do-able and reasonable when compared.
At least my level-3 second level account can complete nearly all to reach the final achievement without spending excessive resources: the most draining was the total 2T spent on 2x 80% players task. All the rest can be completed with reasonable use of blue packs before our key cup and league title decider matches.
Stage 20 completion by 2nd team account
And that helps unlocking the free 7* player referral reward of 1st team account
Just need some squad planning and we all could get some reasonably nice rewards. Much much better from Nordeus with some improvements on the tasks given that freeloader accounts can do them all without excessive resources spending.
