Tight spaces and obstacles make playing with fissures a hell

I love the druid and playing around the fissures but tight spaces in maps like dreadnought or random objects on map or even the bosses can stop them from expending or stacking on top of each other.

As a warrior this wasn't really a problem since you wouldn't keep spamming while stationary but when using the druids fury of the mountain you are expected to slam back to back to back to create those multiple fissure where it becomes a problem.

While this doesn't ruin the gameplay it makes it feel really inconsistent as sometimes they work fine and I can deal proper dmg and sometime the fissure don't branch properly and won't get created/stacked, lowering the dps drastically.

Hopefully GGG fixes this with a small QoL update. What are your experience so far with the fissures?
