Tune Senna to be played ADC, not support.
People play her and she is garbage tier support, can Riot change her to be ADC ? Like the idea was nice on paper but dont work.

Senna is a suboptimal ADC due to her limited synergy with crit/attack speed and her lack of good sustained damage.
Her heal and CC make her more than capable as a support. Try building Duskblade -> Athene's with Aery + Revitalize, and see how she feels as a support.
Riot already said they would be willing to tune her more towards support, she is not focused on being an adc shes meant to be a support and shes really good at it
People aren't building for her budget. They're trying to build damage. That's why it looks like she sucks.
She most definitely works as a support (and an adc and mid for that matter). The problem is that people are A. Playing her wrong and B. building her wrong.
Senna hasn't even been out for a day yet, give her a patch or two before declaring that she's dumpster-garbage. I Guarentee you that that once people figure out what's the best setup/champion combo for her, she's going to be really popular.
Remember last time people said the new support was weak and useless?
I 'member 
you are probably just playing her wrong. get the positioning right, build the right items, and just in general play better.
What a boring idea.
It has been less than half a day, give it time.
