How do you think this new team size limit of 5 changes things?
What do you think will be the best teams now?
I expect the 3 best teams to be 5 shamans, dk + 4 palas and 5 dks. All 3 might be around equally good.
Druids are probably going to be a little weak now when they can't burst things down so easily, can't get healed as good and will be very vulnerable to cc.
Priests feels like they will be a little worse than druids. Same disadvantages but missing some of druids advantages.
Will there be less alliance multiboxing teams?
With a high team size limit the racials doesn't matter much, but now with only 5 characters allowed I feel like Arcane Torrent and War Stomp is going to be a much bigger problem to deal with for alliance multiboxers.
Could 5v5 arena get active?
When every multiboxer plays the perfect team size for arena, maybe it could get active. Although because it is so dead it might not happen, when 2 teams queue and one sees the other will win all games that one will stop queueing after 1 game and then it is dead again, unless it does the weekly 10 games and don't mind the loss.
Any other differences that might happen?
In WG a multiboxer won't be able to solo defend around a corner of a wall anymore and it won't work good to attack cities with just 5 characters.
Not sure what else will really change.
