I'd like to see an update which will allow us to switch the inkling's weapon hand. Pressing left stick or the never-used L button would be valid options for this imo. It would definitely deepen the game's meta.
Great topic and analysis, flc. Now I know why I always felt more comfortable to play on the left/west side of Rig. I knew this peeking technique (if you want to call it a tech) was around for some time, but I didn't imagine it having such a great influence.
I'm hesitant about banning Rig right away, though, but with the game's current state and the information we have, there won't be good alternatives. Even if you were able to counter the peek advantage, it would put you at a disadvantage, because the other team wouldn't have to worry about it.
