Same thing as calling almost any move with an invincible start-up a DP.. Or calling all disconnected hit-box, long distance travelling moves fireballs or projectiles (the latter being the better blanket term).. yes, maybe the move looks like something else, or has a different name, but you know what's being talked about when someone says it.
Shrug, I mean, I get both sides, but ultimately, if you say Smoke's Spear is this or that, we all understand what he's talking about.
Also, guessing is the nature of the game. Things are better now than they ever have been IMO and really, I dont see the issue with spending a bar to make something safe, but it still being negative. I mean, as a defender if they blow a bar so I cant punish, but its now *my turn* - I have no issue with that.
