Well its not that OP of a passive if it procs before other dmg reductions(armor,mr).

Lets assume you and your team have 100 armor/mr and you also have 300 AP(lvl 18 ofc)

Enemy AP carry has 600 AP and deals lets say 600 dmg with one spell.

You would get 92 dmg reduction and 46 on allies.

You take 508 magic dmg further reduced by mr to 254(no magic pen for simplify)

Without the passive you'd take 300 damage,which means this passive reduces this damage by about 15.5%.On your allies its half effectiveness so 7.75%.True,its op versus low damage attack and spells like singed's poison,but against nukes its uncomparable to lets say Poppy's passive which grants about 30% reduction in most circumstances.

About the lack of chasing skills:

Well,every champion has to be balanced after all,and since he gets a soraka style ulti that also grants full map vision and gives you one global damage spear..i think its right to not give him any more mobility than its needed.
