I don’t see what they can answer except something typical like – We are aware of this situation and the devs team is looking for solving it in some future update.

All those things are legit and I don’t think it bothers much nordeus.
Someone can create and have 50 TE accounts (which is good for marketing, presenting high numbers of users), those teams doing a massive vids farming every day (which is also an income for nordeus) and those few teams are a challenge for all the other common players which are the rest 99% of players all over the world.
Most of them are not even aware of what is happening there .
How many regular and active members has this forum, 1000 ? 2.000 ?
Few more thousands from some TE fb groups and that’s it.
Personally I don’t mind of that issue as those mutants are used only in Platinum asso tournaments and my group decided to stay and play for fun only in Gold.

As solution I can see two ways.
One is to change the whole training system – Drills/skills/white-grey skills/ min-max % prices/ effect in game calculations.
Back on the roots of TE 2014.

The other solution is to demolish the associations ranking system.
Platinum and other divisions, top100, high token rewards.
Just playing with asso groups and get a weekly or monthly small reward.
Top 100 exhibition is the best place for those tricksters to show of or advertising their "product" for selling.

both are painfull so don't expect much @agusbandung11
