TBH they could make the game somewhat decent by simply making same type bonuses (like gold from gems, superheroes and hero skills) MULTIPLICATIVE.
Everything beeing additive hurts the balance of this game and makes it nearly impossible to progress much further than 100 (unless im missing something).

Im currently stuck at 109 with about +9000% dps from my active dps superhero. This gets added (NOT multiplied) to the few hundred % bonuses from hero skills and the 12% from guild bonus (LOL). Its the same for gold and click dmg. So basically the guild bonus is pretty much pointless is comparison to the other bonuses and there is no way id make any progress by rebirthing for gems. Farming the lvl 100+ bosses to keep getting gems (without rebirth) seems to work only on the original version btw, on Nutaku i killed the lvl 100 boss for hours but only got 2 gems from the very first kill.
