I wouldn't blame Ensidia for Saronite Bombs exploit. Ok, they got world 1st by using that but that's Blizzard's problem. They should have "fix" that before launching the encounter. The ones who I'd consider exploiters are he ones who will use this after finding our about the bug.
Still, I admit that is not fair to others that they got the world first kill by using that exploit...

Dunno what to say rly and I'm curious what the solution to this problem will be.

Its not an exploit, its a creative use of game mechanics.  Now that Blizzard 'fixed' it, it is now an exploit.  It is like russian roulette on the top end encounters.  Do we use everything available to us, or do we limit our creativity.

Something is an exploit once Blizzard declares it as such.  I'll use Mind Control for example.  In the battlegrounds, a priest could use mind control to kill people by throwing them off of very high places, such as the lumber mill.  Another thing that mind control could do was force people out of the battleground by walking them thru the instance portal.  The person that got walked thru the portal would be flagged as a deserter and have to sit for fifteen minutes before requeueing.  In this case, the victim would be told it was a creative use of the game mechanics.  This form of griefing was not punished, but eventually fixed.

In the case at hand, Blizzard didn't conceive that this would occur.  They did not code against this possiblity, nor did they determine that this was an exploit until after it happened.  Ensidia utilized a creative use of the game mechanics to beat an encounter.  High end raiding pushes the limits of the game.  They down bosses with much less gear than the average raiders, but the get the benefits of buggy encounters to beat.  I used the Russian Roulette analagy because being creative could possibly push a raid past the line between creative use and exploitation.  Besides this case is minor compared to their downing of Lady Vashj.
