SO HOW ABOUT 1 SPEED ATTACKERS?
They have nice guns and useful utility, sure.
But is their utility game-changing? Not really.
Of course, Fuze can come handy for clearing utility on some objectives. But it’s situational and you clear defensive utility with a well-planned combination of operators and smart usage of their utility (both universal and unique gadgets).
Gridlock, on the other hand, can be replaced by Nomad for covering flanks and lowering movement potential of defenders on the site, too.
Are their guns unique only to them? Negative.
Fuze’s AK is also available to Ace, while his LMG can be equipped by Finka. Gridlock’s LMG is accessible by Capitao (3 speed). Sure, her AR is currently only available to Gridlock, but that gun is far from being OP or a reason to pick her instead of other operators.
On attack, you have to move a lot. The speed at which you peek and advance your push is an important factor in winning rounds in R6 Siege.
So in my opinion Ubisoft should just change Fuze’s and Gridlock’s ratings to 2 speed.
1 speed attackers will not be a thing in Rainbow Six Siege unless they are shield operators.
Also, I may be wrong, but neither attacker would all of a sudden become OP with such a solution.
