[Suggestion] Improving Thor's Ult

[Moonstruck]

Firstly, I want to say that I think Thor's ult is fundamentally great, but there are a few tweaks I'd love to see.

• Allowing the player to slam down whenever they want
  
• Adding a new "charge up bar" where the longer you charge the ult, the more damage it deals, scaling from, say, 40% dmg >>> 100% dmg

Why do I think these changes would be beneficial?

Looking at ults like Scarlet Witch's, its long charge-up time makes sense since it's an insta-kill. Thor's ult doesn't really compare on that level.
95% of the time when you ult with him, people just run away because of the extended charge-up time. Adding scaling damage would give the ult more practicality while still adding a trade-off for triggering hammerfall/slam down early.

Another bonus is that it would make obtaining Thor's achievement a lot more manageable.
