If there is another dreadlord hero, I'd like to see

(1) Visage - Take the appearance of an enemy hero that is furthest away from you, appearing as an ally to the enemy team for the next 8 seconds. Taking damage or casting an ability breaks the effect. 70 sec cooldown

(Q) Glide - Fly in the target direction, blinding enemies for 1.75 seconds and reducing their vision radius by 25% for 3.5 seconds. Auto attacks increase the duration of the vision radius debuff by 0.6 sec.

(Trait) Blood Hunter - Enemies at or below 30% health are revealed on the map and grant the Dreadlord up to 40% move speed based on how far away he is. When a nearby enemy hero dies, you are healed for 20% health.

® Summoning Ritual - Create a rune circle anywhere on the map that remains for 3 seconds. Allied heroes that stand in the circle morph into green nether energy that travels quickly to the Dreadlord’s location. 70 sec cooldown.

® Mind Flay - Channel an enemy hero for 3 seconds, dealing 180 damage per second, burning 7% of its resource and 15% spell power per second. The spell power debuff lasts 6 seconds after the channel. 45 sec cooldown

Thats all. Just a few ideas. It will probably be a year or so before we get another Dreadlord, if ever.
