Quoted from InfiniteLives:
Why are you not in modes? Like, 95% of that game should be played in a mode. If you are not in a mode, you shoot the mode start or the GAT to start a mode. Or, if you arent in a mode you are probably in a wizard mode, cause you better be stacking your multiballs with a mode.
Nero stack then play destroy the drill, extend the mode, hit the GAT shot, then just crush left orbit all day. Then, play save the Enterprise, same thing, hit your black hole to extend mode, hit a shot and then GAT, then crush left orbit all day. You can forehand or backhand it and you get a safe return or hit some warps from the return.
Then you have super spinner and left orbit banging, and you end up with a ton of points.
I'm not arguing that you shouldn't be in a mode most of the time. I'm arguing that your not getting 2X, your just getting credit for a combo. Meaning that in your example above, after you complete the Nero stack and are playing DtD, when you hit the left orbit, regardless of if it's a combo or not, you only get 2X.
If you were really getting 2X for completing Nero, hitting the left orbit on a combo would yield 4X.
