Orcs – discussion about the race.

Did you even think about what you wrote, suggesting to nerf already weak Orcs?
And with a Warlock, you can cast spells as much as you want, especially at a developed level; Bloodlust will work, but very weakly.
While you're getting your Orcs to the enemy, you'll already be shot down with magic, and no amount of Bloodlust will help. And you can miscalculate by developing Anti-Magic against a Warrior!

No, at first, while their Blood Fury and Chaos Suppression aren't leveled up (when playing against a Warlock), they are weak. This is when you need to take them out. But what if the opponent is far away? The Orc will develop Chaos Suppression, skills from this branch, Blood Fury + War Cry - what will you do?
There's a skill in the Chaos Suppression line that increases the enemy hero's mana cost by 50%. And considering that when playing as a Warlock, it's more profitable to use spells enhanced with Arcane Wave (which is another +50% mana), the "cast as much as you want" option won't work.
