I think the change to Kyre was appropriate, because it was pretty strange seeing an entire army fall in a ball underneath his feet after his pull move. However, with this nerf and the nerf to the speed of Eldritch winds, I think Kyre is somewhat weak and too easy to avoid for a 5 point elite. He provides very little utility other than his pulling move, so this should be made strong again, or he should be given some other function. His melee DPS is low and true damage is hardly useful on a melee unit, because the opportunity to go 1v1 vs enemy armour is extremely rare. His winds don't do enough damage to make him an effective nuker, and are slow enough to simply walk away from for most units.
I don't think Kyre is weak, per se, just easy to counter-play and predictable. I think he either needs some buffs or a rework, and here are my suggestions; they are not intended to be used together, but could be.
1: Make Kyre the Eldar Diomedes
Kyre's critical strike gives shield regeneration in a circle, but because he gets focused down he's hard to keep in combat, and doesn't deal a lot of damage in melee anyway, so it's too risky to send him in to melee. Eldar have no elites that provide healing to their units in battle, and because they are so vulnerable, could definitely do with this to give them more staying power in the mid game. I'd like to see Kyre given a role as a 'whole army healer' like Diomedes; he could give shield regeneration to his whole army with his critical strike, similar to Diomedes. Alternatively, Eldritch Winds could give some shield regeneration to the whole army that's proportionate to the amount of damage it deals - so, even if they do only mediocre damage against upgraded units, allowing your units to get hit by this attack would strengthen your opponent's forces. Another way of implementing this would be to give shield regeneration in the Eldritch Winds area.
2: Buff Eldritch Winds and Plasma Grenade Barrage
With his pull nerfed, Kyre could do with his other abilities buffed. Plasma Grenade Barrage is very weak against single targets, and because his pull no longer scatters all units under his feet, it's difficult to hit many units with it. It's damage should be buffed considerably so that it's worth to actually use this ability, because as it stands, I don't feel it's worth the risk to the hero.
I'd also buff Eldritch Winds alongside this; I think it would be really cool and flavoursome if Eldritch Winds caused enemies to levitate, like the SM orbital bombardment does. This means that Eldritch Winds would be a very useful crowd control method so he can support an army. Since the winds are now avoidable, I don't feel this would be imbalanced. Furthermore, since Eldritch winds takes so long for him to cast, I think it should really wreck a lot more havoc when it reaches enemy lines than it currently does.
3: Buff Kyre's Presence
Kyre's Presence is pretty lacklustre as it stands. This is for several reasons. Firstly, by the time Kyre takes the field plasma grenades are not really relevant to the fight any more. Secondly, because I can just build more Dire Avenger squads at that point of the game if I want more plasma grenades, there's not really much need for the ability. Also, plasma grenades don't scale well because of the knockback caused; I can't bombard a single target with plasma grenades to destroy it, at least not efficiently, because the units are scattered over an area reducing AoE. Thirdly, I think the presence is weak in general; as a presence, it should really have much more of an effect on your army, not just let them use an ability they already have more often; compare to Terminator's presence, which turns heavy bolters in to a completely different unit.
My suggestion is to add something on top of the additional plasma grenades to his presence. Perhaps Dire Avengers could be given deployable energy shields with Kyre's presence, or give free reinforcement for Dire Avengers.
Thanks for reading. Like I said, I don't think Kyre's weak, just that he needs a gentle nudge towards viability again, and think this is an opportunity for him to be made a much more interesting elite.
