i would tell beginners to use stuff like that sparingly, because if you dont even have a grasp at basic tools, just throwing out situation stuff will only punish the beginner's game some more
those tools are useful i agree, but if you dont know how to use them properly you will get blown up hard lol. for someone like star who is having a hard time just starting this character in cs2, i would just tell him to stick with the old stuff until he gets better. i dont see how someone who is having hard time hitconfirming basic strings would be able to properly use and fully hitconfirm a special combo with 6c ch, tk double palm fc, or 3c fc starter.
imo its better to tell a player what he already knows or heard just so it gets drilled down that much, so that they start implementing it into their game, but also mentioning the kind of stuff dacid mentioned so that they start seeing when they can use it right while theyre learning the character
