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.
