But why do this when you can put in similar effort and make a team that can clear 5/6 elements instead of just one?
No, it's not. It's about making the best use of limited resources, including time. Just because a strategy works doesn't mean it's optimal.Your question is more akin to "how can I be super lazy and still get everything I want?"
Let me rephrase the question. Under what circumstances is it better to invest equally in teams for all 6 elements vs. investing primarily in one? And under what circumstances is it worse? In what timeframes?
