Completing any of those gives a random chance. Is it effort when people come in at the last minute, do nothing, and get an exotic? Is it effort when people afk and get exotics? No it is not. Is it earned when someone goes into their first ever strike/crucible match and gets an exotic? no it's not. There are some people that put in way more effort, and do these daily, weekly, and monthly and never get anything so by your logic unless anyone gets an exotic then they have wasted effort, but if they just happen to get an exotic it's not wasted? Does the lottery require effort good sir? No, it doesn't. People buy a ticket and hope for the best. If the best happens then it didn't happen through effort it happened through luck.
