Why are followers not allowed to be interesting if they are grouped with Runeterran champs whose Origins are only "Play me with my package"

For clarification, the two Runeterran champions who fit the "bill" for the title are Evelynn and Jax. Both of which whose only effect is "you can put x in your deck." I'm also not gonna talk about Jax himself being boring cause that's a different issue.

This is something I've noticed before with Evelynn's followers, and is a thought that has been subsequently reignited by the reveal of Jax and his followers.

Their followers are fuckin BORING.

Each of their followers follow the same bland shit of "When I'm summoned, I do x" where x is their packaged mechanic.

Evelynn has 5 followers, and three of them have the exact same text, of "when I am summoned, summon a husk."

I will admit, the last 2 followers left, Domination and Solitude, they do at least try to interact with their mechanic with their 1 drop buffs, along with their I summon husks of course. Alright fine then, lets move to Jax.

Jax now released, he has 4 followers, and guess what?

There is only a single follower that doesn't simply say "when I'm summon, Improvise", and it's Wandering Shepard, and the ONLY DIFFERENCE he has is that he gets to choose ANOTHER ally to improvise when he is summoned, rather than himself.

.

The worst part is about it all, is that it's clearly not a creativity issue, this issue doesn't happen to their spells, it isn't even shared among other Runeterran champs.

• Bard, despite having only 3 units, still has more to his followers, while Byrd is just "summon me do mechanic", Esmus has a function outside of I PERFORM MECHANIC with his support ability and Maduli allows chimes to explode in potential by doubling them

• Kayn's Cultist units all interact with equipment in unique ways, with a predict effect that reacts to equipment, a power share effect, and a token generator

Jhin is a little unfair to count since his followers by nature couldn't have been "I DO MECHANIC" since he is based around play effects, but they are still varied in what they did with stuns, recalls, deal damage and kill effects.

You'd think that if these Runeterran champs main restriction is being locked out of one other region and forced to use a certain group of cards instead, their units would at least be designed in a cool way.

I get that maybe the thought process is that if they are gonna introduce a new mechanic they need a baseline that just simply does it, but when these champions have only 4 to 5 followers, they really really can't be having more than half the followers be that baseline.
