You don't need to eat poison to know it bad for you. You don't need to play a game to know its bad. In the real world we can use things like statistics and feedback to make accurate and unbiased judgment on a topic without witnessing it first hand. Most of the destiny community are extremely biased and base things off of "I can deal with it just fine" or "it's not as bad as other things in the game" or "people nerfed Hunter when they said it was op but now people think Sunbreaker is ok only cus it's a Titan". While a professional will simply look at the numbers, see how many kill Titans are getting per super on adverse and how many time they are shut down on adverage and other statistics that will show the unbiased facts.
