[quote] instead of using game exploits to beat the Templar and Atheon. [/quote] Bungie has not come out and ever said what is and what isn't the right way, they have only given vague objectives like defeat the boss. Now players are using the game mechanics to their advantage, however this doesn't mean using the advantage is against the rules of the game. Simple put if the devs give you the option to find different solutions to problems by using different game mechanics. That just means the devs succeeded at making a difficult game and not making a punishing game. For example you are allowed to go to that platform in the Templar fight.(no invisible wall was placed to stop players from going there.) And the atheon fight, He avoids sustained damage attacks (certain grenades), and smart players will use this to control the boss .(this wouldn't be an issue if he didn't have that AI protocol.) Generally speaking game mechanics are being exploited(made full use of) to find non-standard solutions to the encounters. Now this may not be an issue if the devs are going for a dark souls style of letting players find solutions to fight bosses, vs a WOW approach where they nerf or patch any non-standard solution.(class stacking, or using certain buffs against bosses by kiting mobs from other fights into the boss room to later steal that mobs buff) This is a good video regarding this discussion (the dark souls example primarily): https://www.youtube.com/watch?v=ea6UuRTjkKs
