Mana tick is higher in combat

[sadpanda353]

Describe the bug i get 4 mana per tick out of combat and 6 per tick in combat, EDIT: Added 2 picture, look at the chat someone did some test there is something wrong.

Steps to reproduce

1. use mana and test both

Expected behavior Prob just inverted ? should be 4 in combat and 6 out of combat

I can confirm mana regeneration doesn't seem to be accurate at this moment at least compared to Vanilla. For reference I'm leaving this here: https://vanilla-wow-archive.fandom.com/wiki/Mana_Regeneration

Things to note: Five seconds rule and no mana regeneration at all while casting (at least according to that wiki).
