Thoughts and Discussion: Shyvana
Let's get right to it:
~ Shyvana doesn't have a passive, I am thinking of something like take her current Q (lower the power a bit) and move it to her passive with a cooldown that also reduces faster with her attacks - freeing up a slot for a real spell. (her "passive" can simply be she gets slightly more base stats, like 5 more armour at level 1, rather than remove 5 armour to give 5 armour for a "passive")
~ Shyvana's identity as a damage-tank is great, but just having damage is not a good reason to pick her because if you want damage you pick someone like Fiora and if you want a low CC super tank then you pick Dr. Mundo. So granting Shyvana something more special, in some kind of utility sense for her team, will give her a real reason to be picked over anyone else since she does that cool thing.
~ Shyvana is the fire breathing dragon that we all want. Unfortunately this is not really there right now and it be cool to make Shyvana feel more like a dragon, a super tough and hard hitting power house, but also just making her abilities feel more dragon-like in some form. For the record Burnout (W) and flying through the air with Dragon's Descent (R) are really cool abilities, also I feel are unique to Shyvana, so making her other abilities feel equally as unique should be something to go for here.
Fury of the Dragonborn (Passive): Whenever Shyvana damages an enemy champion or monster she gains 3% damage reduction for 2.5 seconds, up to 30%.
Dragon Form: Shyvana gains 5% damage reduction for 2.5 seconds, up to 50%.
Twin Bite (Q): Cooldown: 10/9/8/7/6 seconds; Range: 350 units Passive: Shyvana's attacks on-hit reduce Twin Bite's cooldown by 0.5 second.
Active: Shyvana unleashes two fire balls in the shape of a dragon's head in the target direction dealing 20/35/50/65/80(+100%AD)(+50%AP) magic damage, applied in two instances of damage, and exposing wounds for 4 seconds. Applies on-hit effects against struck enemies two times.
Champion basic attacks against these exposed enemies deal 11/12/13/14/15%(+4% per 1000 health) of the target's total armor and magic resistance as bonus magic damage (min 15/17.5/20/22.5/25 damage).
Dragon Form: Shyvana lunges forward.
Burnout (W): Cooldown: 12 seconds; Range: 150 / 450 units Shyvana surrounds herself in flames for 3 seconds granting her 30/35/40/45/50% bonus movement speed that decays over the duration while dealing 30/45/60/75/90(+20%AP) magic damage per second to nearby enemies. Shyvana's attacks deal 25% of this damage as bonus magic damage on-hit.
Burnout's duration can be increased by 1 second per basic attack from Shyvana against non-structures, up to a maximum of 7 seconds.
Dragon Form: Radius triples.
Flame Breath (E): Cooldown: 4 to 10 seconds [on key release]; Range: 750 / 350 units Hold Down Skill Key: Shyvana breaths fire towards the mouse cursor dealing 5/6/7/8/9%(+2% per 100AP) of the target's maximum health as magic damage per second (max 100 vs monsters), stopping at the first enemy champion struck and splitting off into a "T" a short distance. Shyvana can freely attack and move during Flame Breath.
Flame Breath can occur for up to a maximum of 6 seconds, cooldown increases based how long Flame Breath lasted for.
Dragon Form: Reduces magic resistance by 15/20/25% for 4 seconds.
Dragon's Descent (R): Range: up to 850 units Passive: Shyvana can cast Dragon's Descent when she acquires 100 Fury. Shyvana gains Fury while in her Human form at a rate of 1/1.5/2 Fury per second. Both in Dragon form and Human form Shyvana gains 2 Fury per basic attack. While in her Dragon form she loses 5 Fury per second, upon reaching 0 Fury she transforms back into her Human form.
Active: Shyvana transforms into a Dragon and does an unstoppable dash to the target location, pushing enemies she makes contact with while dealing 100/175/250(+70%AP) magic damage. Afterwards Shyvana remains in her Dragon form and enhances her basic abilities.
UPDATE: Removed the ground on Dragon Burnout since Q can apply on-hits synergising with Frozen Mallet, radius size is more dramatic with less normal radius and tripled while in Dragon form.
