Regular fans are like minus 8 on block, even if you can't punish you should at least get something after on block unless they back dash or armor, but all her armored moves are full combo punishable on block. Square wave, lift, rising fan, and throat slice. Ex fans are very safe/good though. It sounds like someone's getting away with stuff. Her down 1 has a lot of range, but it is eight frames, down 3 is meh, down 4 is okay. She probably does good againt Erron, but nothing unsafe sounds like someone's abusing online.
