I’ve lost numerous flags even within TFs , i attack the person capturing it, the game process my attack, the flag remains white, the person stops the capture animation (and i can see the attack animation) then a moment later we lose the flag.
Not mentioning u can capture a flag now within a single CC, they reduced the CC duration on rogues so in normal BGs they cant cc u and capture the flag like in DF, but in blitz they can, anyone with a dedcent cc can…
Reducing the required time to capture the flag dont make blitz a faster mode, it just make the game less balanced and comp dependant.
Now healers are sitting bases, carrying flags, everything…
They even harder to kill than in normal BGs…
Now with faster ccs healers are terrible.
And blitz combined all of this, blizzard must rethink blitz as a whole.
But i like capping base in one kidney shot. 
Just nerf rogue cc. Simple.
