I would like for them to do away with the random spawning seeds and make it so she gets to upgrade one of her spells (only one)
Q: Upgrade: When Zyra gets 100% attack speed from items
When Zyra's Thorn Spitter plants shoot a thron at Zyra's target when she auto attacks them doing 1/3rd her auto attack damage as magic damage. This attack is counted as an auto attack and applies on hit effects and is in addition to the plants normal attack.
W: Upgrade: When Zyra gets 100 AP from items
Zyra's seeds last 30s longer and act as a ward. When a unit dies near a seed or plant allies near the seed or plant gain regrowth. Double the effect if a Champion dies near by. Zyra also gains a Seed when a Large minion or monster dies near her and two seeds if a champion or epic monster.
Regrowth - Gain 150% hp regen and 75% mana regen for 3s.
E: Upgrade: When Zyra gets 300 Hp from Items
Zyra's Lasher Plants enrage for 3s if they attack a immobile champion. They attack in a AOE around them and their slow is +30% for a total of 60%
Then change her Ult to do about 75% the damage it does now but creates a Zone for 6s. The zone applies grounded and any plants spawned in the zone are enraged as well as plants already in the zone are healed to full.
Then make it so her Plants start out with 16 hps and lose 4hp/s for 3s. Enraged plants have 32 hps.
