Yes, I realise it was a bug but it was such a good mechanic. It could have been toned down so it only went 15m instead of 23m which was OP.
More combo based abilities would make the combat more interesting and raise the skill cap.
I’m generally against more CC (we have too much in group battles) but just for example - Scream into Oblivion roots everyone in the Oblivion but for a shorter time.
Fireball into Meteor storm creates a giant meteor.
Splinter shot into poison cloud spreads the poison.
Charge in to Gravwell expands the well.
Just some ideas off the top of my head that would make things more interesting and maybe revitalise some of the unused abilities.
