No. These wouldn't make GNB better, they would make the job worse. If you don't like weaving and don't like having to manage your resources to have enough for your burst window - play a Warrior or a Paladin. Bloodfest sitting at 90 second cd is the one thing keeping GNB's gameplay from becoming static like the other tank jobs. We have 4 tanks, one of them can afford to require a tiny bit more engagement and apm than the others. It is still very simple compared to some things we've had before SHB.

The only QoL change GNB needs is increasing range on the Continuation abilities, so that they don't cause issues while moving bosses.

At most, if people are really that heartbroken about Double Down, it could be changed to be usable with only one cartridge for half its potency and full potency when consuming two.
