(2) Sed's Inspiring Roar applying a 15% speed/15% evasion aura in a 15 y radius
also - if you are talking about applying this to any creep in her radius, that is op without a doubt. She heals creeps already with healing wind... add an evasion + speed aura to that and just by walking with some creeps, she could likely lead the creeps to crushing a citadel in short order. My comments were based on the aura applying to dgs only.
Huh? 24 hps isn't significant at level 15. Many demigods will single-shot every creep except Giants and Catapults at that stage of the game.
15% dodge compared to 15% attack speed from fire aura... since dodge only works on autoattacks (and spit) the dodge will only be significant when Sedna is "pushing" a creep wave alone (she can pounce a giant, then move back and let her creep wave win). However, she gets 0 gold from doing this.
Basically, this change would enable Sedna to lead a creep wave extremely well. She still wouldn't be able to content any other demigod in a creepwave.
And, yes, Fire Aura, Surge of Faith, etc, all effect creeps. I'm amazed you didn't know that. In fact, Fire Aura and Surge of Faith affect minions TWICE, in terms of the speed benefit (base minion speed is based off of the general. If the general is moving faster, so do the minions. If a minion is also buffed with Surge or the aura, then they move even faster from that).
