Nah.
Don't forget siegfrieds WR AA, 1AA, 6B+KK, and a few others.
I honestly dont think Astaroth is that easy to win with unless you're spamming 66k/1A all game.
Scrubbiest has to be in terms of lag tactics:
Mitsurugi (By far the most easiest character to win with. 2kb, 1a, 11k into A from relic stance. etc)
Siegfried (LOL we all know why he's here.)
Ivy (Also we all know why she's here. I hope static won't troll me for putting her here)
Amy (66:B Spam? Can't punish? Too bad. Oh wait you see A+KB but can't sidestep? Too bad.)
Sophitia (236B! 236B! 236B! 1K! A+B!)
Lizardman (236A! 66A! 1K! people abuse 236 online like crazy)
In terms of no skill in online play:
Maxi (Sorry HRD we all know why he's on this list.)
Kilik (ASURA DANCE HOOOOOO!!!!!!!)
Amy (Lol what a coincidence. Just use 6b and 6B+K and 44B!)
Nightmare (I CAN DO IZ 236KK AND I KNO HOW TO DO 3A+B and 1A!!!)
Talim (A, A, B, B, A, A, B, B, A, A, B, B, .... 4B+K A!, B, B, A, A)
Mitsurugi (Derp B, B = I outframe uz, B6 and 3A makes me cool.)
Cervantes (....nuff said)
In terms of just general abuse:
Hmm...Can't think of anyone o.O maybe Vader since you can easily abuse BB into 1A+B on noobs who crouch A+B
That being said some characters actually have to work to win online
Cassandra
Rock (Considering how laggy online can be against pure lag tactics, Rock works his ass off for a win)
Voldo (Yes I personally think voldo has to work to win ONLINE)
Yun-Seong (Cmon besides the fact most people fall for the Neutral Crane Stance, he still has to earn his win against lag whores)
Taki (Debatable but I feel if a player isn't being frame happy she also needs to earn her win)
Vader (I don't know but I feel as if 6A+B can't JI grabs online...and some of his frames feel slower like 6BB or 8-way A+B)
That being said it does come down to the player in general, but we all have those moments were we call out a character for being total scrub sauce (SIEGFRIED!!!!).
