Yea I used to main Karthus,

So my response to this is. If you start casting ult at the start of a battle (to say hit all 5); if the enemy is close to you they will disrupt chanelling and the spell is wasted. If you cast it too far from the enemy, then you are not likely in a good gank opportunity and they will withdraw from combat, and again the spell is wasted.

Using it at the towards the end of abattle is very beneficial, if fact I would say a necessity - it picks off fleeing heroes, allowing possible ace which will get towers down and allow you to push much easiler
