Nope. If you have S5 Sampo cones you can give Hysilens that instead but her S1 is VERY good. It gives partywide SPD which is the rarest stat in the game. I wouldn't get E1 right now unless you just want DoT to kill everything for the next 4-5 months.

Kafka does not need her S1 anymore, use Silver Wolf 4* LC. Do you have Black Swan? She's not necessary but she's a good 3rd man.

The thing about DoT is that it's super niche and if you're going into it, it's very expensive. If you started Day 1 or you lucked into it, it's still a good backup team but it's always going to be gutted by its mechanics more than anything else because DoTs don't carry over onto new waves. It has and will fall off hard because they don't support it often.
