already seeing mordekaiser in my games

And they mention an outlier. As if it ever mattered.

"Hey, look at this exception. Look how important it is." Bah

Yeah!

Why isn't your name "Shenpai Noticed Me"? Immortalize your love in name and deed, Melledoneus! Like me.

not a bit to do with both

a bit to do with buffs or nerfs, a lot to do with pro picks.

I don't have my notes available on this computer, but it's happened 4 times in one game if I recall correctly.

(morde and blitz cannot actually burst him)

This is where I completely disagree. Let's see the damage that Mordekaiser and Blitz can deal at levels 3, 5 and 7, within the CC's duration (granted that Azir can't WQE before Blitz knocks him up, otherwise there's a high chance of him getting his dash cancelled).

Level 3: Blitzcrank's Q deals 135 damage, assuming he put a second point in it, his E has a 2 AD scaling. We're assuming Blitzcrank won't use his AA reset, lest Azir escape in the meantime (If Blitz takes W at level 3, this won't change anything as it will allow him to use a second basic attack during the knock-up, for a similar amount of damage). Mordekaiser's combo (without the third Q) hits for 175 + 3.6 total AD + 2.25 AP. Assuming Mordekaiser has AD marks, that's a total of 175 + 288 + 70 + 135 + 134 = 802 damage, before taking the ignite in account.

A level 3 Azir with Doran's Shield has 702 health. After 27% damage reduction from the resistances, he will end up with less than 10 hitpoints after taking the ignite in account.

Assuming he is full health. That would mean that he never took any minion damage (thus didn't even try to attack Mordekaiser at all), and that Mordekaiser never hit his W or E on him.

Level 5: Blitzcrank will deal 190 + 3 AD, Mordekaiser 285 + 3.6 AD + 2.25 AP. That's a total of 1086 + 150 true. Azir now has 862 hp. He's got a bit more armor, but no additional MR, so let's average his damage reduction at 28.5%. That means he'll take 924 damage, and be ded.

Level 7: There, Blitz and Azir will only be level 6, due to Mordekaiser's passive. I'm going to count, in order:

• Blitz Q x1
• Blitz R passive x1
• Blitz R active x1
• 4 basic attacks from Blitz (one during the ult's silence, then the attack reset with the E which deals the damage of two attacks, then one during the stun thanks to the AS boost).
• Morde Q x2
• Morde W x2
• Morde W - Recast
• Morde E
• Morde R - 13.3% of Azir's max health over 2 seconds
• Morde ignite

Mordekaiser recalled and purchased a Blasting Wand. That means that the combo will deal 540 + 4 AD for Blitz + 340 + 3.6 AD + 2.25 AP for Mordekaiser + 13.3% of Azir's health + 190 true damage. Which equals 540 + 308 + 340 + 360 + 155 + 125 = 1828, 448 of which is physical.

Let's now count the resistances: 1344, or 1534 with ignite. Azir has 942 HP. All of this supposes that Mordekaiser doesn't even have DFT, and has Stormraider. I didn't take in account the damage-enhancing masteries - the damage would on average otherwise be 8% higher from Mordekaiser.

Do you really think Azir can't be bursted down by them now?

would be better off with a soraka keeping you healthy enough to farm

Absolutely never. As Mordekaiser, you want to have a support tank that provides engage tools. Never a sustain/poke support. You want Blitz, Thresh, Nautilus, Leona, Trundle. You want someone who can go forward and start applying your W, as well as speeding you up, before you can join the fray with your mace. You want someone who can provide CC for you to deal your damage. You want a towerdive buddy. And you want to make sure that your team won't lack engage tools, since you neeed these things as Mordekaiser.
