You're new to loot based gaming, aren't you? I know it hurts to be wrong, but check your ego... it's getting in your way. Destiny is a "looter shooter" though these days Bungie prefers the term "collection game". I can guarantee you that none, literally none, of the people farming strikes are doing so for the sake of showing off their leet skillz. They are doing it for the loot. Problem is there's no seperate matchmaking for farmers, and using 3rd party apps to find groups to speedrun heroics is tedious at best and impossible with certain modifiers active. This means that farmers will have to resort to standard matchmaking which in turn tends to pair them with non farmers. For farmers, loot is the incentive, not the enjoyment of strolling through the park shooting stuff, which means that if you want them to slow down, there needs to be a something to encourage them to do so. The best way to do that is to make the entire strike relevant in regards to loot instead of just the boss/end chest. The best way to do that, without making it rain loot, is to score strikes and tie loot chances to scores with higher chances at higher scores.
