A Reasonable non-combat buff to Zyra's seeds(Rampant Growth).

The main buff I desire to see would be an increase to the duration of true sight on enemy champions that step on/destroy them.

I believe 5 seconds would be on par with most other sight abilities but at least 4 seconds is needed in my opinion, either way 2 seconds is pretty weak.

That being said I'd like to suggest an additional non-combat buff to her seeds in which they would last for 60 seconds but only able to grow(become spitters/lashers) for the first 30 seconds.

For clarity, the seed could have a mini animation before it changes to it's un-growable stage, at which point it changes to a darker color, but still retaining the ability to apply true sight to enemy's that step on them, perhaps at a reduced duration.

I feel these buffs are not only needed but would add some flavor to her kit.

Don't forget, the main goal is increased duration of true sight, with increased seed lifespan being a bonus if possible.
