Plants are cool, but 2/3 need work
Most thing in league have a give and take or decision making around it. Plants are freebies and should not be.
Blast cone should be an escape/distance closer but at the cost that it does damage with decisions like will i survive the explosion? If i do i getaway. As of right now it just makes already mobile champs more mobile for free. Or free getaways all around
Honeyfruit isn't really interesting at all...free heals, might be more interesting to broaden their spawn areas (in lanes for instance) and have a clear animation of them blooming, upon full bloom it gives regen for a certain amount of time up to a cap, while standing in its aoe. It becomes a point of contention.
scryer's bloom works because you can reveal portion of the map at the cost of potentially revealing your own position as a jungler.
