i still think it was done by accident and now they call it a new feature to cover up the mistake that was being made.
i honestly believe that the replays should be from the boss that actually got killed at that stage of the game and not some pre-patch with different heroes. what i am saying is that IF it shows a clip then that clip should be from the actual boss to beat with the same power, same resistances, etc ...
i dont care on what server or what player has beaten him first, but i think its fundamentally wrong to show clips with 20% less power. to be honest, what is even the point? the only similar thing is the name. i watched some clips on previous bosses getting beat using cianna + shayd where the boss stays in stun almost every round! that same boss i did a test run and beat him everytime because i have double the power. so instead use of full form i used my main and cianna as only heroes to hit the boss and got a result that lets your hair stand up: 3 out of 100 stuns cianna was able to stun him!
to add insult to injury i have to point out that in the clips i see heroes taking 4+ hits from minions and bosses before they go down. my heroes usually get 1-2 shot on the same boss if they dont dodge.

that being said, i have a message to the tynon team and developers:
if you screw up and your old data gets lost and you replace with even older data to cover up for your mistakes, then at least admit it and say say sorry to the players. instead of posting insignificant and out dated clips you could have just left it empty and collect the new material and show the new clips.
IF however it was really your intention to show the first down from all servers on all servers at once, then you should have made the bosses equal to beat for all servers. this way all they have similar is the name.
now my suggestion for the future on how to fix this and get customers happy again, i would suggest to wipe the clips and make the first five downs from servers with EQUAL bosses available for viewing.
