Ardent Censor rework concept

We all know is a broken item rn and nerfing it will do nothing, just another cancer item will be buffed instead, so why not rework it

Cost: 2300 build path: + + 600 25%_Bonus mana regen 50 AP UNIQUE: 20% CDR UNIQUE PASSIVE: your shields and heals grant allies 10%-20% AS for 4 seconds UNIQUE ACTIVE - Full Chalice: for the next 6 seconds your shields and heals are 30% stronger and grant allies 20%-40% AS and 20-40 on hit magic damage for 4 seconds. 90 seconds CD

Balance philosophy: Not as powerful when rushed as it currently is, mana regen is on bonus only, not base so becomes much more powerful after 2 items. AS down and no on hit damage. no constant shield/heal buff. the active compensates for it gives stronger effect all around, more as more damage more shields and heals, however does not last as long and has a window opportunity. also gives 20% cdr instead of 10 to allow to be used more during active and took away MS.
