Meh, I don't really like the build. I've tried something similar to this after the patch hit and it's just not as good as your conventional LeBlanc build. 20 Magic Penetration actually makes a huge difference. You lose 15% damage per ability between level 1-11 and that's a lot.
I'm not sure you really understand how magic penetration can affect your damage. Just look at how effective MR really is at reducing your damage (effective MR as in the calculated part after you've subtracted the Magic Penetration from the opponent's Magic Resistance):
10 MR = -9% damage
20 MR = -16% damage
30 MR = -23% damage
40 MR = -28% damage
50 MR = -33% damage
100 MR = -50% damage
Flat Magic Penetration works a lot better early on as you can see both MR and MPen are more effective at lower numbers and both decreases in effectiveness the more you get. Squishies have a base MR of 30 and typically don't invest in any early MR either so having 30 Magic Penetration means you're dealing an effective 23% additional magic damage per ability. Of course the limiting factor to MPen is that any MPen that tries to reduce an enemy's MR below 0 is worth nothing... but people could probably argue the benefits of simply just doing full damage over less damage regardless of the worthless value of the stat after a certain point.
Still: MPen > AP > CDR for LeBlanc. CDR is nice, but I don't think you can make a valid argument for prioritizing it over MPen except to just be different. It's not really better in most ways outside of giving you a little extra help for running away and maybe tacking on that clutch Q once in a blue moon that could maybe net you that kill. Ionian Boots vs Sorc Shoes changes how LeBlanc plays by a lot more than I thought and I've actually found that the extra CDR lost me more kills than it got me since the situations where I need the additional CDR come up less frequently than the amount of situations where I just need to straight up burst the enemy down. You can't rely on Ignite to cover your loss in damage especially when it's on a 3 minute CD.
She does not fair well in team fights, the best way to do team fights is to snowball as mid carry and pick your targets for insta kills.
She can take out a specific target, and silence them for 5-6 seconds but overall she does not do well in team fights.
You just bide your time, pick your target, and let lose, root some people if you can, silence the spellcasters, that is about it.
I haven't read the replies, but I find it odd that you suggest Frozen Heart for your armor item in light of the fact that you tout the Ionian Boots as the only CDR you need if you Blue Pot constantly. That's wasted CDR, the mana isn't needed, and if you need armor I think the better item is the new Hourglass. It grants 100AP, 50 Armor iirc, and the old Zhonya's active just in case you need it. Grabbing pure defensive items on caster/assassin like LeBlanc just seems like wasted itemization. She can blink twice (or three with Flash) to escape, but if anyone gets on top of you that you can't nuke down, you're going to die no matter how much armor you have. I'd prefer to have that bonus 100AP and active compared to mana I don't need and CDR that goes well over the cap.
I would put BV into this same boat, but it does give you MR which is what you're more likely to be poked with at her range, and the bubble could save your life on rare occasion. The health goes well with Rylais at least.
You should never need a Void Staff. The targets you should be targeting will have low enough life and MR to make it unecessary. The only benefit this has for you is if you want to help your team kill off the surviving tank just a bit faster. And if the targets you're going for are stacking MR specifically to kill your burst, all the better for your team because now they're own damage isn't what it needs to be to fend off everyone BUT you.
I'm not saying you HAVE to go frozen heart, in fact it's only necessary if you are being focused a lot and they have a full AD team, even then, not really. I then go on to say that items are completely situational and you should look at your enemy team and base your decisions from that.
Obviously if you go frozen heart you probably won't want to get the CDR boots, be sensible, I'm not doing any hand holding this is an advanced guide. Also FH is rarely gotton on LB i jsut suggested it if your being focused a lot by DPS, meh,
Thanks for the reply.
