This "fact" is commonly repeated, but if you crunch the numbers (as Vexenu did in the thread he linked earlier) it turns out that:
So if you agree with Vexenu's math that means that instead of:

Here's a link to the Vexenu's post since no one else linked it:

The problem is that Vexenu makes some really terrible assumptions.
Most glaringly, he magically gives his erudite necromancer a 700 mana infusion every hour on the hour. In reality he needs to make up the 1800 mana per hour, not 1100.
Then he calculates "additional liched medding time needed" rather than comparing mana/hour to mana/hour. His comparison is wrong for multiple reasons:
1. Comparing this way skews ratios (much in the way that 1/0.95 != 1.05/1.00)
2. it neglects that this additional liched medding time is going to cost even more hp
3. It gives the illusion of minutes per hour yielding some true percentage, when in fact one is not even close to always medding (casting, pulling, etc.)
Let's assume for his lvl 54 necs that he's medding 80% of the time and standing/casting 20% of the time, with lich on constantly.
600 ticks in an hour: 480 sitting ticks, 120 standing ticks
Normal Mana Regen: 20 mana / tick when sitting, 1 mana / tick standing.
Lich Mana Regen: 20 mana / tick from lich
HP Regen: +5 sit, +2 stand for Erudite, +12 sit, +6 stand for Iksar
Lich HP Loss: 21 per tick
Mana Regen: 19320 mana
HP Loss: Erudite - 9960 ; Iksar - 6120
Mana Cost to Regain HP: Erudite - 4980 ; Iksar - 3060
Net Mana Regen: Erudite - 14340 ; Iksar - 16260
At this point, we have 16260/14340 = 1.134. So you have 13.4% more non-BoD mana for the iksar - not enough to make up for all the xp penalty, but much better than what was cited before.
If we repeat the same analysis for lvl 56 regen, all else equal except for:
HP Regen: +6 sit, +3 stand for Erudite, +16 sit, +10 stand for Iksar
We end up with:
Net Mana Regen: Erudite - 14640 ; Iksar - 17460
At this point, we have 14640/17460 = 1.193. So you have 19.3% more non-BoD mana for the iksar - enough to make up for the penalty.
Once you get to 60, there's another bump in regen.
Note: In reality, you are not really getting 2 hp per mana unless you never lifetap. It will normally cost you more mana to regain that hp, but this analysis is also discounting the 2 damage / mana that you're doing using those BoDs (as compared to more efficient DOTs).
That being said, a lot of time in this game is spent standing and running places, moving around camps, etc. Being able to run with lich on (and then with it off, to regen) is very useful indeed. And being able to regen quickly to full HP without needing a mob to tap around is also useful.
EDIT: if you consider a more realistic HP per mana value of 1.75, from a mix of lifetaps and BoD, the values go to 16.1% and 23.1%, respectively. And, as stated before, adding in more realistic scenarios with wipes, having to recover or go AFK while FD, more standing time spent pulling, etc., then iksar clearly evens out and pulls ahead.
