Thing is that the XP plan is not even good.
Why split XP on both Ignition aura & Alfa & Omega?
Is there any justification for the purchases?
Build comparison
I'll go over the abilities & spells we can level, and try to argue for or against spending XP on them.
Flight:
This gives maneuverability and nebulous dodge bonuses. It's OK to spend XP, we will want levels in it.
High-Speed Combat:
We will need this against fast opponents: It's OK to spend XP but we don't need it now.
Ignition Aura:
This is a mixed bag, before Incineration it has low damage and does not do much.
With Incineration it's very good with extreme damage.
We should think of it as a very good ability that costs ~4000 XP.
Focus on it or ignore it don't mix.
Plate Armour:
This has a low base multiplier but it has good scaling at 30% per level.
It's the best defensive XP investment.
Armored Soul:
This has flat scaling making it very bad at high levels.
Only reason to spend XP here to survive resilience bypassing effects.
Thermal Control:
This is super good, but it's level 17! so it should be.
We don't need XP here yet until out other abilities begins to reach this level.
Regeneration:
The ability is not good to level since we can't get more HP cheaply.
As it it's out of combat recover and getting more would be to expensive. Don't spend XP here.
Reinforcement:
This is a OK ability. The math says one should by 1 level for every ~6-7 levels of Infinity edge. (+30% vs +5% and Infinity edge gains extra attacks).
For best gains spend XP here once Infinity edge reaches level 50.
Alpha and Omega:
This is a very good ability with terrible synergy with us. It's power is that it eventually wins any attrition war.
But we are a glass cannon against almost any opponent we will either win or lose long before this becomes a factor.
It would be perfect for Daiyu, but for us it's not good.
Don't spend XP on this.
Plasma Sphere, Thermal Spear & Push:
Good spells but since we have spell boost we should level Infinity Edge instead. Don't spend XP here.
Halt:
This is a good spell we should level this to a multiple of 5 to gain the level bonuses. OK to spend XP on.
Infinity Edge:
Spell boost is literary a game changer, it changes how one should think of XP and spell damage.
Levels in this gives: Melee damage, spell damage and, extra actions.
It even gives some defense by improving hungering void and resilience.
If we focus on this every new spell we get will be resilient.
Best offensive XP investment.
