Yeah, but this was midscreen, meterless combo that started with 2a. Warc 2a5b2bc5c j.bc j.bc does 4.6k without crits or damage reduction (I cant do the extra dash j.b lol). Nanaya 2ab5c2c5b j.bc j.bc combo only does 4.5k to vAkiha. Miyako 2a5b6b2bc5c 236a6a j.ac j.bc meterless corner combo does 4.8k. I imagine the only meterless 2a combos that can touch 5k on her are Akiha and Arc corner combos. Those take some execution. For such an effortless combo to do 5k damage, even with shit defense, that is ridiculous.
Edit
According to Benny who tested out the Arc meterless corner combo damage for me, her basic 2a5b2bc5c 5abc 5ab2b4b j.bc j.bc does 5.4k. One of the highest damage meterless combos in the game, a corner combo with pretty decent execution requirement, does 5.4k. sAkiha did 5k with an ezmodo combo. Now tell me that isn't ridiculous.
With reduce damage and criticals turned off, Aoko has 5036 meterless midscreen BnB on VAkiha with 2a5b2b2c5c3c jc jB dj jb jC tj jB jC. In corner
2a2b6a6b623A starts combo
whiff 2a 3c covers tech backwards, tech forward, and no tech with VAkiha blocking if she neutral techs. She takes 5125 if she doesn't tech, 6144 if she techs backward, 6918 if she techs forward.
5a5a5b covers neutral tech and missed tech with VAkiha blocking if she techs backward. Neutral tech results in 7379 damage and no tech takes 5381 damage.
If they respect that enough to not tech, you can do a combo that does 7923 damage(this one actually requires decent execution.) Heat punish combo with j[C] j[C] airthrow does 4899 damage(real combo does a bit more)
