Items I'd like to see

I've been playing League for a while, and there's just a few "holes" in the item library that always bugged me:

• A Tank item that has lifesteal/spellvamp. Currently, all damage-to-health items are heavily offensive, and tanks without self-heals essentially rely on regen. It'd be nice to see something that gives me some sustain in lane, like something that adds 10% spell vamp to an item like Sunfire Cape.
• An AD item with Armor. There's AD+MR, AP+MR, AP+ARM, but no AD+ARM item. And it's not like the item would be useless, it would be a good synergy for most fighter champs
• An Item that builds out of QSS for mages. Currently, it builds out into AS or AD, two stats full-blown mages care virtually nothing for. So if I want to get out of CC, I either have to rock a Banshee's or Mikael's (which are both defensive, and Banshee's doesn't let you choose what CC you dodge), or have an item slot devoted halfway to stats I don't want.
• Something that builds out of Crystalline Flask. I get that it's a starter item, but even Doran's ring/shield/blade have relevance until your item slots build up, while Flask falls off fast. I'd like to see an item that simply gives good passive health/mana regen, with an active that boosts it for a short period, or gives the bonus to nearby allies for a short time. I feel like it'd be a good support item
• More items with auras. Something that would make more teams work together/close by instead of the soloQ splitpush rush.
