I'd disagree on Athene's - you say you don't need CDR just because Vel'Koz is an ultbot, but firstly:

1) anyone who's an ultbot kind of sucks. Looking at you, full tank.

2) you complain elsewhere that W and E have long cooldowns. So... um... fix that?

3) People don't buy max CDR on because her ult cooldown is really long, do they?

CDR on Vel'Koz makes you a better kiter, skirmisher and sieger, and there's not really much else to go for - Abyssal? You said yourself it's not actually that great late, and Athene gives you almost as much MR, with spamhappiness to dominate your lane just as hard as getting Abyssal would get you.

Oh, any you misunderstand MPen at one point:

"That means that with 30 spell pen from boots and Majora's Mask, you will ignore a total of 60 MR: 30 on the first hit, 30 on the second."

MR reduces damage by a percent. If they have 30 MR this modifier is about 23% reduced damage. If you have 30 MPen when they have 30 MR, they take true damage. This is a constant multiplier - you don't ignore 60 MR if you hit twice.
