So far none of these reasons are legit. You don't win by being "faster" you win by being smarter. It's just like the game of football, just because your faster doesn't mean your better and are gonna score all the time. You gotta be smart and sneaky. When i see enemies doing that i aim right for them, whereas when idk where they are i panic when trying to find it
Sorry but you are exposing yourself as new to the game by dishing out bad advice.
There's plenty of times you can win by being faster - when the opportunity presents itself. The flag juggle is very useful in many situations. For example, when the enemy is respawning and you want to be fast. Or when you've been spotted and you want to be fast. Or you can throw it to a teammate that's up high and they score, cutting out a longer route and making you faster.
There are obviously times when you want to be sneaky too, like when you are alone and have to pass enemies. But you don't have to play that way, it's just another option.
I see that you haven't even played Arena this month, so is there any reason that you consider yourself qualified to tell us how to play the game? Have you played it at a high level with a good team?
