Why don't we have an AP Upgraded item for QSS?

depending on the champion you're using for very little defenses(at least in Zhonya's case) and up to 30 less AP(in most cases), while also losing out on the damaging actives/passives of these items(Ludens for example that's 400+40% AP damage cuz 100+10% AP per target). It's a big difference. Banshee's passive is terrible as well and Zhonyas' active is situational. You're trading really good items with good passives/actives for really mediocre items with situational or just flat out bad passives(Banshee's Veil imo is probably the most worthless passive I can think of because of how easy it is to just pop and walk off then go back in when your cooldowns are back).
