Bug: `AutoBalance.LevelScaling.EndGameBoost` is overtuned

[kjack9]

Current Behaviour

Enabling AutoBalance.LevelScaling.EndGameBoost causes low-level dungeons (< 75) entered by high-level players (>=75) to be overtuned. Damage becomes unsurviveable, especially on bosses.

Health seems to be not as extreme, but still is likely overtuned.

Expected Behaviour

Low-level dungeons entered by high-level characters should be tuned appropriately to match the other dungeons at the player's actual level.

Steps to reproduce the problem

1. Enable AutoBalance.LevelScaling.EndGameBoost in the config
2. Create a level 80 character and equip with level 80 heroic dungeon gear (https://www.icy-veins.com/wotlk-classic/protection-warrior-tank-pve-pre-raid-gear)
3. Ensure GM mode is DISABLED so that AutoScaling will adjust the dungeon
4. .go creature 39934 (Bloodmage Thalnos in SM Graveyard)
5. Let his shadow bolt hit you
6. Die

Extra Notes

I will triage this issue in the next feature PR by disabling the feature by default in the config. In the mean time, I recommend everyone disable the feature until the intention of the feature can be restored.

I will be looking at this again after the next AutoBalance release - I think I may have fixed it while working on other things.
