Umpires in helmets?

It would seem that umpires have been giving helmets consideration given that the ball is being hit back at them so hard they are struggling to take evasive action in time.

I wonder which traditionalists would like worse - umpires in protective equipment or video umpiring to avoid the issue altogether? On that note it seems this Ashes series will not be subject to referrals. England should be happy with that - more wrong decisions gives the weaker team a greater chance of victory (dare I say, as in 2005).
