What I don't like about Senna is she can shoot her teammate (shielding them) and go through and her the enemy. She can use a range ability to damage tower (though that isn't new as Tristana does it with her bomb).
But what makes this disgusting is that scaling range. Sure one can argue that she needs a lot of souls to get ridiculous range...but she hits so hard, and a fed Senna can make up those souls quick.
Ult...ok fine I can deal with...
That annoying Root Shot...sure
The fact she pretty much as a leech/drain hp...something that should be changed.
Being allowed to just outpoke range...Thats sickening, I hate dealing with Caitlyn...get both of them on enemy team and enjoy how top lane feels when melee goes against range...
People throw around "overloaded"...but compared to all the crap she can do...yeah...someone with that much utility should have nerfed base stats at the very least.
I don't mind her kit, but either her kits need fixed...or her stats needs reduced to balance it.
Making it one or the other (defensive or offensive capabilities)? I feel like they would overclock the viable options honestly. But I like the concept of it though.
Not disagreeing with your idea...just know what Riot would do to ruin it.
P.S Sorry...I went on a bit of a tangent there lol
