Cool features of Wotlk reals on mop?

Now i aint sure if these features are on all wotlk realms, but i tried to play on blackrock a bit and Arena spectator feature, arena match replay feature(i adore this one!), advanced arena preparation where consumables are already out and crystal to mark yourself as ready so if everyone is ready arena can start no waste of time, all these futures are simply awesome.....

so if all this stuff has been programmed already, why not implement all these to Frostwolf as well? would really bright the grim abandoned mop realm quite a bit

These are the Amazing features of the ArenaTournament Cores (Unfortunately only "AT Woltk" survived after the merge), so only Blackrock ("AT woltk") has them, at 99,99% you will never see any of theese features in the Blizzlike realms because they are not Blizzlike feature.

its not blizzlike in a worse way than 7x higher xp and drop rates than retail like on frostwolf?

they are good features, shame not to make a realm better than it is...if the code could be ported to other expansions it would make the realms alot more fun
