Well I didn't mean it as an insult, more of a joking tone. I do think you overreacted, but regardless I could've worded it better. I apologize for the statement, I didn't mean to insult you.
Here lemme help by stating the basics for anyone thinking of entering the contest.
To get any points at all in the contest you need to do 4 EX'es and one AAD (the easiest option) or you have to do 6 EXs, really difficult.
In blood heat you can barely fit four rapid fire EXes in and then mash out the AAD. So doing 5 EX's then AAD is impossible. You don't have enough circuit to do it. No one does EXes fast enough. Ciel and Shion cheat and are the only people I think who stand a chance here. They can cancel EX moves.
In regular heat you can barely fit in three rapid fire EX'es, then you're stuck with 200% meter. This means, assuming no extensive combo after heat mode is over, you're stuck with only 5 EX's. This means you're forced to do a long combo. Even if you can do an extended combo you have to also use EXes. The people most suited to do this are probably people who can reset slam/bounce count.
Sadly some people stand no chance in this contest. Nanaya cannot compete at all. His only comboable EX is 623c. So his only option is 2 EX kicks and then AD. Kouma also has a hard time, EX grab cannot be used. EX Flame is difficult to use as you cannot combo off of it normally (needing a ch setup and thereby probably nullifying its use), EX Kick is hard as there isn't much you can link after it. This leaves Kouma with the same problem as Nanaya, only one easily usable EX to combo with. But in this case EX punch doesn't even combo into itself unfortunately.
