You are basically complaining about not being able to block a 50/50 on reaction.
Noo... I'm claiming her low/mid mixup is the most powerful in the game and doesn't follow the 'principles' of SC mixups.
Let me try from another perspective. Ivy's low (2A+G) is OP, and doesn't follow the principles of SC mixups.
Principles of Soul Calibur lows:
1) Lower dmg than character's best mid mirror move
2) Slower than mids
3) If high dmg and fast, then low is unsafe
So, If the low is high dmg:
1) slow 2) unsafe
If the low is quick:
1) Dmg is low, or is unsafe
Ivy's 2A+G is high dmg, quick, and safe. It also completely synergizes with her 2+BK moves, and makes them both much stronger. This may be the truest, purest mixup in the soul series aside from A vs B throws.
Equal dmg is Typical of 50/50s
Aside from throws, no. The low option is almost always far less dmg (like half), or slow, or very unsafe.
We'll look at the mixups options for SC2, since that's all I know (but i think the newer soul series are similar in principle). We'll assume the mids are combo'd.
Xianghua:
MID : 3B (60~) vs LOW: 3A (25~
[less dmg, slower, unsafe]) (CH 3AK, 3B is situational)
Soph:
MID: 3B/44B (55~) vs LOW: 1K (25~, [
less dmg, slower, unsafe) or
1AA (slower, unsafe)
Yosh from 1AAA:
MID: WSK (~60) vs LOW: FC3K (25~,
less dmg, unsafe)
NM:
MID: 3B (70~) vs LOW: legsweep/flapjack (30-40~
less dmg) or 1A
(unsafe, super slow, unsafe)
Cervantes:
MID: 3B (70~) vs LOW: 1K (20~) or 1A
(unsafe, super slow)
Now look at SC6 Ivy.
MID: 2B+K (60~) vs LOW: 2A+G (60~;
SAME SPEED, SAME DMG, and SAFE ON BLOCK',)
Hey man, if the developers want to buff everyone's lows, that's fine and i'll deal with it lol. I'm an ivy main too if ivy stays like this i'll just have an even easier time winning, but lets call it for what it is.
