How to make walking calamity a better and more interesting skill

So im playing a druid level 55 HC trade league and started using walking calamity in my build. I like the ability its really cool and does a lot of damage, but I dont like the fact you just press it and forget about it. All of its damage is completely passive. It think it would be cool if you could control where the bigger meteors drop. My idea was to have maybe a certain amount of charges you can use while the ability is active, 3-4 meteor casts maybe? I think that would make the ability way cooler and more engaging than it is now.

An active component would round out the skill really well, another easy solution is to make it call down multiple bigger meteors on cast and then the usual passive meteor shower over time.

This would also create a new archetype of going all in on rage generation to call down big bursts of meteors as often as you can instead of stacking increased skill duration.
