(I dunno if this should be posted here or somewhere else, but it mostly has to do with items, sooooo...)

I don't like being melted in 3 seconds flat when I'm building tanky. Armor and Magic penetration is noticeably stronger now that they've nerfed every defensive item and put ridiculous armor penetration items in like Black Cleaver, and the mechanic changes to flat and percentage penetration.

I feel like it's not worth building tanky now. Anyone else think the same thing?

I would build health if you see they jumped for black cleaver. They can't get much out of armor pen if your not building armor.

Well that's true, but my main problem is that if you don't build armor and you only build health, you're going to get melted just as fast.

I personally feel that there's no incentive to build tanky at all, since come late game, you will die extremely fast.

As a Nasus user, this makes me sad, and it makes me wonder if I should just go straight damage on Nasus instead of tanky, because at least I'd get a really strong Q off on an opponent and dying rather than a weaker (comparatively) Q and dying. >____>

I agree. I usually play tanks but its impossible to build tanky enough to last more than a few seconds. Right now the only champs that can do anything are those with big bursts.
