HaHaHa.
Are you serious? Do you think after the release of 5, developers worldwide will start making 6 in 2D?
How can 3D ruin everything?
Only if it's implemented poorly.
By the way, your colleagues claim that not only 3D will ruin the game, but also the magic school, the ATB bar, the battlefield, cartoonish heroes and units, Town Points, etc., and so on—you could go on forever.
So the game was already irrevocably ruined about a year and a half ago....
..... for you. :)
HaHaHa.
And I will be playing the beautiful, brand new FIVE with a feeling of euphoria and divine rapture.
While you keep running around in the greyish, albeit cute, 3 and wait for 6, although I think you should wait for Heroes 8 — that's where it'll definitely be 2D. :)
