As for future set ideas....
Work sets:
Construction sets, luck sets, product drop sets, and exp sets are always highly regarded. Maybe some hybrid sets, with speed, money and Labour points mixed in too.
Please, really think about level of % bonuses (product, $, exp, luck, speed, regen) included in those sets. Last year created sets were smashing current tombola benchmarks at the time (P. Revere, fisherman, free sets apart from Easter waste were fine too). This year, unfortunately, you have started to give sets with bonuses powerfull as single item of sets mentioned above.
As a "suicide dueller" I´m collecting them kind of from collectors duty - if I behaved "economically", I would spin only for free, because premium medals have much higher game value, than the most of your current year creations.
For example fisherman weapons (apart from rod being for some stupid reason 2 % $ weaker than net) are quite fine idea, how new things should look like > they aren´t the best weapons for product drop, but they are very respectful alternative (to Clyde and Martha) and giving me more money for "shortage" of products instead. Idk if it´s only my opinion, but I don´t need bombastic sets, which trashes current benchmarks by a country mile, just small steps forward or some interesting new alternatives on par with current benchmarks.
