What's with all the stat for stat passives being removed?

: AP for Armor : CDR for Attack Speed : Magic Resist for AP : Armor for AD and now : Mana for Health? What's next? can't have health from AP or AP from health?

If they were potentially "unhealthy" for the game then why put them there in the first place?

I mean I understand that keeping the same passives with some of the reworked champions will make them look unhealthy, but changing their passives on champions that were ALREADY fine ( , , ) makes absolutely no sense. Not only were they smaller scale reworks, but that also forced them to use only ONE build, making them weaker for the better or worse. In other words, making them less useful in other play styles.

As singed you could build three AP items and still fit one or two tanky items in your build to be more versatile since his ultimate doubles those amounts. NOW you can only fit Rylai's because now , is pretty much less important with his old passive now gone. Meaning, there's only one build you can go, the one where people can chase you and take no damage. Except the part where they changed his W to be really good now.

The bonus magic penetration would be unnecessary if it was still on Xerath since he now has 4 abilities instead of 3, but why did his AP for Armor get removed? You basically don't even have a passive with being your first item and all. I mean it was probably to give him some counter-play, but look, this is his counter-play: / / . He's forced to go full AP runes because if he has any cool-down reduction runes he doesn't deal enough damage in the early game to pressure the enemy laner and saving your E for that perfect gank doesn't do shit when the stun scales with how far it travels.

And finally Rammus, I actually don't see the problem with Rammus in this state other than building AD on him. He used to be able to build Thornmail and just straight up crit and armor without any items with attack damage on them since his AD scaled with armor meaning you didn't need to build damage if your attacks dealt physical damage, which now his kit is entirely magic damage. Rammus is no longer an AD Bruiser OR AP Tank Hybrid, he's now JUST an AP Tank.
