The Tomb got harder recently?

Because it feels like for me. I started trying the EE or just going in to pew pew some criticals (almost ever with 3 randoms, some good, some bad) but the last like two days i feel like there are sooo many Amalgams and Doppelghast spawning even in early rounds and that they eat my bullets like peanuts. Also i had some higher rounds around the 40s with just any two guns. Now I'm using meta guns and barely make it past 20. Even with the Amr that i really like for the special zombies seem to not hit register properly. Is it me who became worse or something has changed for real?
