Seven and Haze 4 skills

[the]

What does everyone generally think about them? I feel like they are weird outliers compared to the rest of the abilities, that generally require more coordination, while needing way more work to counter (ontop of items like refresher and majestic leap that make them so much more severe and unpredictable). Is this a skill issue and these Ults have legit counters i haven't figured out yet? or do other people think similarly?

[BEEP!]

Seven is easy to deal with if you have any type of stun ability you can just stop him and his 4 works on being in a line of sight so just get behind something so if you see him don't fight him in the open make him fight in a closed off smaller area.
Haze her 4 well it splits damage between how many are around her so you can negate a lot of her damage just being around a group of creeps or team members just don't let her catch you alone.

That's what I found out by playing as them and against them.
