Overshadowed by Manaflow Band/Nullfying Orb? Lmfao. The only players using either were 1) Supports who spam mana inefficiently and 2) Champs who have high mana costs like
.
And it's not that we're upset with Domination being mage accessible.
The problem is it's ALREADY accessible, and they are moving all Sorcery's strengths over to it.
70% of players Diamond + use Electrocute already. It is by FAR the best Keystone for sealing kills.
Comet and Aery are "nice" but they RARELY ever impact anything other than being an inconvenience. Laners hit by them just farm/heal to get back into it. Electrocute almost ALWAYS occurs when trying to land a kill/ensure a kill.
You have no idea how many of my Morgana kills come from going through my whole combo on one champ, and then auto attacking a second and killing them with Electrocute on Q + a couple auto attacks. They don't expect it, have calculated that all my abilities are down, and just..... keep fighting, only to have that third hit knock them for 300-400 damage.
Relentless Hunter has been a mage's go to rune since in came out, due to its out of combat status vs the fact aoes don't all trigger combat, and length of cc's. If you are a mage and don't have Relentless Hunter, you die on average 2-3 more times a game than someone who does. It's arguably more important than any other rune (ofc Inspiration Magical Footwear users will disagree, but same principle).
You're right that Manaflow + Ultimate hat opens new doors, but it also essentially locks users out of other rune trees. You pretty much MUST go Sorcery/Domination to pull that off now, when in many situations, you need Ultimate hat + Resolve or + Precision.
And there's only a handful of mages who actually need Manaflow Band. I've played all these without it and done fine:

There's other ways to get mana, and most champs just aren't expensive enough to need it. The ONLY champs I've played that seem to need Mana sustain, are
, because they have insanely high costs (and They've been bringing Lux's down) The rest generally don't have many problems once they have 1-2 items.
generally ensure that.
