Earlier i gave examples of characters who's KBs were either too good or basically useless, but characters with decent, fair KBs i think are
- Sub zero: 3 unique KBs with good damage and fair conditions.
- Baraka: Able to string KBs together for chunky damage if necessary, at the cost of optimal damage compared to separate combo KBs. Suits his aggro but honest base moveset.
- Scorpion: Really well fitting KBs that are fun to use and flow naturally, rewarding good gameplay.
- Kabal, though i may be biased as he's my co main, has really fair KBs. B12u2 is safe and hit confirmable, but has surprisingly tough timing to combo from and doesn't net much if you miss. Hook Slam is much easier to combo from and does amazing damage, but is unsafe normally. F224 is meh, i think it should either do more damage, or less and popup for kombo.
And on that note, so should Skarlets b2. I have many more suggestions, and opinions, but I'm using my phone and it's... Not easy
