I have to agree.
Gear Tetris has reached a point where optimizing a setup takes many hours - not playing in game but spreadsheeting outside the game. Many and likely even most players, even some that have played for years, simply give up either entirely or just follow a guide someone else wrote without really understanding exactly why.
I kinda enjoy it but only kinda as its also quite frustrating - in particular if you farm rare stuff and it turns up not stacking as expected.
That said - please add Quality Spell Focus Mastery +2 and Insightful Spell Focus Mastery +3 somewhere in Dino crafting.
