[Wraith Suggestion] Dynamic Ultimate Cooldown based on distance energy left

Hello everyone,

I have a balance suggestion for Wraith's Ultimate (Dimensional Rift). 

Currently, whether you place a maximum length portal or a micro-portal of just a few meters, you consume 100% of the ultimate charge and have to wait the full cooldown duration.

The Idea:

Implement a proportional energy refund system. If you open the portal and only use 50% of the available distance energy, the remaining 50% should be kept in your ultimate meter once the portal is placed. Your next ultimate recharge would start from 50% instead of 0%.

Why this would be healthy for the game:

* It rewards quick tactical thinking for short-distance repositioning or saving downed teammates.

* It adds a high-skill expression layer, managing ultimate energy dynamically.

* It makes Wraith feel more fluid and useful in close-quarter skirmishes without changing her core identity.

What do you think about this change? Would it be balanced?
