Nah sorry, but I don't agree with Lukz here, some people will enjoy longer games if they really enjoy the scheme, look at me, I will happily sit and watch hours of other people playing Darts... And I ain't even playing lol...
This is basically like saying, I don't enjoy that scheme, please make the pain go away faster, how can that possibly be fair for the people who do enjoy it?
Personally speaking, I don't like football, bores me to death, so no way i'd watch 90 minutes of it... Why not make football 10 minutes each half? Well, even though I don't like football, I think 90 minutes is good to give both teams a fair game, playing diff tactics and what not.
Also, regardless of the rules of BnG, it all comes down to how good the players are, if they are on form, games will be faster, if they aren't on form, games will last longer.
Lowering the health of BnG makes it less competitive, it's not uncommon for players to have a horrible start, go behind, then pick up the pace, play better make a well earned comeback, and win, lowering the health ruins this, I love this tenseness of BnG, it's one of the reasons I enjoy clanning.
If the player who hits 1st pushes their opponent, then they move, and get hit again, and again... 200hp is good to give that chance of a crucial shot to turn the game around and have enough HP to last it out to give a fighting chance.
