I think the sword block should of stayed.
It was an advantage to people with good connection and is a 50/50 chance you will survive or not.
Even if you sword block, it takes away all your health and you can not sword block again.
If you are lucky enough, you would sword block and immediately kill your opponent right after.
Like say you have a power weapon of some sort; Sniper Rifle, you sword block your enemy then quickly snipe him after.
It's quite an advantage and I think it should of stayed. 343i could of at least give the players the right to vote, because it's some what unfair to others.
This is all my opinion, just saying that 343i had no right to do this, it is unfair now that the players with the sword have a easy kill on the the people with regular load-out weapons. Sure, there's the shotgun, but 343i should of let the players vote on this one change.
