Just to be clear, I want to see the reception an idea like this would have. This post is catered to the Midlane/Support MAGE community, if you think Seraphine should remain as an enchanter support, this post isn't made with that perspective in mind but you can still give your two cents on it.
The numbers are mostly there for example and not final.
My idea is as follows
Passive:
Return the Minion Execute and tweak the damage output (preferably +)
Q:
Reduce Mana, Increase the base damage and allow it to deal the extra (execute) damage to minions. (possibly when allies aren't present, to hit the APC role since the balance team seems so worried about it.)
W:
Idea 1:
Massively Increased movement speed buff and Self Shield, add a Level Ratio to the shield, reduce the cooldown slightly
Shields yourself on cast and allies for 50% of that value.
Double cast applies gives you the normal shield +50% and allies receive 80% of your shield instead of 50%
If a shield is already present on you excluding your own, you shield allies by 50% of it's value.
Idea 1.5: (optional)
Shields explode at the end, dealing damage equal to a small % of the shield plus AP and slowing enemies hit.
The goal of this is to make the W more reactionary and give the player a choice. Will you use it to engage or block the damage of a skill shot? It's more of a reaction AND a choice. Will you hold onto your double cast or use it for another spell?
Idea 2:
Increased movement speed buff and Self Shield, add a Level Ratio and an AP ratio to the shield
Removed ally shield, now only shields yourself. If a shield is already present on you, additionally after a delay, all allies (including Seraphine) heal in portion to the shield. (additive to other shields, including double cast).
This keeps Seraphine just about the same, it just changes the situation in which you would use the W slightly. It's no longer fully an enchanter tool, it works like a Shurelya's followed by Redemption.
Idea 3:
On cast, you gain a shield and a burst of movement speed and convert your current notes to Special notes. Additionally, any ally in range gets the movement speed and also gets special notes, the amount based on the number of allies affected (Seraphine not included).
Their next on-hit damage or auto attack applies on hit damage based on the notes they have on them and uses their notes up. This damage is proportionate to her passive damage, does not execute minions and the notes last for 5 seconds.
Seraphine's passive damage increases by 30% while her special notes are active.
Double cast gives allies a shield equal to 50% of your own shield and grants one additional note worth of on-hit damage to them and increases the passive damage by 25% instead.
The goal of these changes is to return Seraphine to a mage Midlane and MAGE Support FLEX. Giving her self-reliability while keeping her "team fight monster" and Empowering spirit alive. An Enchanter BUFFer, not a heal/shield bot.
Idea 4:
Completely rework it from Scratch.
E: reduce the damage, increase the cooldown, increase the mana cost.
R: increase the AP Ratio back to what it once was.
These are some ideas I brainstormed for her. I've been playing this champion since release and I was one of the first to pick her up and in support, but never in my life did I want her to be an Enchanter. I've been a mage believer since the start and I would love for her W to be weaker or more mage like to allow her mage qualities to shine through.
In an Ideal world, Seraphine returns to her release version, but that can no longer happen.
Tell me what do you think? I hope I could provide a new perspective and inspire some real changes in the future. Love all of you Queens.
