From my perspective it was poor game design on Bungie's part that they didn't realise players would cheese the boss in that manner from the beginning. The fact that the platforms are close enough to jump on (and can be chain jumped to get to further platforms) seems to indicate that Bungie wasn't opposed to the idea of players using them somewhat (perhaps a way to give a sniper player a decent spot, not entirely without its own dangers) - but they failed to anticipate 6 players hiding on one platform and cheesing the boss from there. Say whatever you want about strategy and creativity. It is fundamentally a cheese strategy. And because Bungie failed to foresee it, they've now had to implement an extremely simple fix to stop it, which has other less desirable consequences (now the platforms can't be used for anything). There are some great suggestions in this thread about ways in which the Templar could have dealt with the players using this platform, like having the Templar teleport players on platforms back into random locations in the main arena whenever he is hit by the shield, or having enemies spawn all over the platforms, or having the Templar able to spawn at adjacent platforms - all of these require time however, something Bungie doesn't have. I can't wait to see the wailing about Bungie stifling people's 'creativity' and 'strategy' when they patch Atheon so he doesn't fall off the edge...
