I know no one will be able to convince you that there is a superior spec to your but as I said and explained it in my earlier post, you will indeed get healing with the build i suggested. Conversion isn't as powerful as you think it is. You also have to factor in what I said and factor in the absorption shield granted from your death strike. You also didn't understand the above poster he said "[font='Lucida Grande', ', ', 'Lucida Sans Unicode', ', sans-serif} ']All tanks (dks included) don't really worry about overall damage/healing taken unless mana becomes a problem, and rather focus on burst damage since that is much more likely to kill you."[/font]
What this mans is that you thought he was talking about dealing damage but he was talking about taking damage. Conversion falls short on a lot of the DS fights and a hot that costs you burst healing and diminishes your active mitigation just wouldn't help on those fights. Now if it was a passive hot with no repercussions whatsoever and had 100% uptime then yeah I'd end up taking that over death pact, but sadly conversion is just not cost effective enough, generally I experience that I won't have enough runic power to sustain it to equal the heal of a death pact. In approximately 16 seconds you will heal as much as a death pact heals. So taking that and adding the runic power cost, that comes out to 10 runic power + 10 runic power a second = 170. 1 rune strike is 30 RP. 170 / 30 = 5.66666666667. RE and RC both have a 45% chance to trigger which is approximately every 2.2 (repeating) rune strikes. 5.66666666667 / 2.222222222 = 2.55. So 2.55 procs of the RC or RE. I'll just say 2 for demonstration purposes. So with those 2 procs that'll yield you with a free death strike (provided you get an unholy or frost rune) with RE which would give you at least 36960 (with a 264k health pool) healing with approximately a 73920 physical (200% mastery) damage absorption shield so if you add the two 36960 + 73920 = 110880 so a total of 110880 gained (minimum, you will be taking damage throughout the fight making your death strike heal more then subsequently grant you a bigger shield) from just not taking conversion and you still have the death pact heal. With RC you have the increased rune regeneration for ~4 seconds (scales with haste and a blood dk's haste isn't that high) which would calculate into something of the same matter, however I feel that I started to ramble a bit there but I could go on and on. I'll leave you with this.
edit: Forgot to do blood tap, but it should equate to about the same. [font='Lucida Grande', ', ', 'Lucida Sans Unicode', ', sans-serif} ']5.66666666667 rune strikes * 2 (charges granted from blood tap) = [/font]11.3333333333. But since you cant get a decimal value of rune strikes I will round down because of how this mechanic works. 5 * 2 = 10.
Blood tap costs 5 charges so with blood tap you will get another free death strike. So, the same calculations apply.
TL;DR death pact > conversion
Your numbers are good but you mistook the approach. Who's talking about using conversion for burst healing? I spoke about using conversion to help replenish your health after using a 5 charged death strike, while the shield remains, although you can also use it in situations of sustained heavy damage.
With the rotation you use, it is impossible to get a 5 charged death strike, as you'll spam it all the time.
My rotation is diseases, spam heart strike and blood boil when procs. You seldom use a death strike (at the begining of the rotation or when no burst damage is expected) to get some death runes and rune strike when no runes available, so you can keep using heart strike. Thus, when receiving burst damage, you can use a 5 charged death strike which gives you burst healing and a great shield, and then you apply conversion to replenish life while the shield is up, but the burst healing is a fully charged death stirke
How often can you use death pact? 2 minutes CD. if receive burst damage after using it you're dead
On the other hand, in less than a minute you'll have another 5 charges for your death strike, and if you're using this for burst healing, conversion is more useful than death pact, as you can use it a lot more often and in many different situations.
