Runes don't regarge individually

[Renox 0]

On the changes page for DKs, it says that runes recharge individually now. This is not true, they recharge exactly the same now as they did before. The only difference now is that, instead of being linked to their type pair, they're linked arbitrarily.

Here's a video to demonstrate.

Runes 1 and 4 are A
Runes 2 and 5 are B
Runes 3 and 6 are C

Runes of the same letter cannot be recharging at the same time.

Not sure what this video is supposed to show... There's simply a maximum of 3 runes recharging at once now, which is stated clearly in the patch notes. If you deplete all runes from left to right, of course they will start to recharge in order. There's no linked runes...

I think what you are seeing is the impact of the abilities themselves not the runes. Some abilities cost 2 runes instead of one (3 for army) and thus eat more runes. So in both rotations there is heavy switching between 1 and 2 rune cost abilities. Hence why rune timing will be all over the place for each one.
