Zyra Is Called Rise Of The Thorns, So Why Don't I See Some Blood?

The most common case for buying or picking up flowers is when people accidentally place their fingers on the thorns which in this case causes their fingers to bleed with a reaction "ow!". When you see a character's leg or lower body wrapped around thorns you think " wow that's gotta hurt a lot " and " blood".

Regarding Zyra's passive, it's takes effect when she dies and suddenly she becomes a half ranged sniper but it takes 2 seconds for the enemy to react upon Zyra's passive so they can calculate the timing when she shoots. Not only that, it's not a fast missile nor a slow missile it's in between so you have an advantage to dodge always.

I don't find Zyra's passive useful in any way since it activates when you die but who likes dying? If Zyra is mostly considered "Thorns" why don't I see some blood effects? Would it be a bad Idea to have Zyra's passive similar to Darius? or maybe have her to cause toxic damage. I don't really have a good concept to come up with for Zyra's passive to be useful when she's alive but maybe you guys can come up with something too but for me I like to think bleeding damage overtime would be a good idea since it matches.
