I have noticed client mana# jumping around on my titanium client for quite some time. I did not take note of it until a few months ago. This occurred at times on live when I played but, probably for different reasons. I never thought much of it.
Prior to making this change, I had changed rule_values regarding mana regen. I noticed mana regen was +2 standing and this was introduced well after classic and possibly after Titanium was relesed, I don't recall. I wanted to fix this so, I changed the rule_values associated with mana regen. This change was not perfect. I knew I would need to alter the source at some point to actually fix it the way I wanted.
As far as guestimating a new formula: This is partially why I posted this. If there is a more accurate formula for mana regen that was in use from classic to OoW or around there, I'd like to hear it.
I played the most on live between SoL and DoN and I do not recall standing mana regen giving +2. In addition, I recall mana regen as a linear function of the meditate skill and never dependant on caster level during the time I played the most. I could be mistaken as I had no reason to actually create a formula.
PS. Your sarcasm is not lost on me
