but it's the preferred means to start one is the point, to show max damage
every combo could be 5b-3c starters since those are the ones that are most commonly started but they don't maximize damage.
and 2C is a good poke regardless, safe, still gatlings into good options, fatals, I just think the majority of us are used to catching people with 66 5B rather than 66 2C to get used to it though, then again 5B feels like just the universal staple combo starter.
you can always TK GH the 2nd hit to catch mashers, which nets more damage, or just jump out and be safe, since there's rarely scenarios where jump canceling gets you into huge trouble unless you've made it obvious.
it's not a -great- tool, but it's better than other options if you're that deep in the string(2D, grounded gauntlet hades, 6D resets)
I personally use it on average maybe every 2 or 3 matches just to keep people honest
