New locket-stoneplate interaction
I love the new locket change on PBE, but am concerned about its interaction with stoneplate -- that would make an otherwise balanced locket OP, since all the stoneplate's additional HP are bonus HP. And if locket is balanced around having stoneplate with it, it would make it uninteresting without, which would decrease build variety.
I am not really sure what to do about that, other than lower stoneplate's active bonus HP (that would reduce other potentially toxic interactions, such as chogath's stoneplate+ult), and bump its other stats:
Proposal: New stoneplate active: +30% HP, 60% if 3+ enemy champions nearby, -50% damage. Increase its armor/MR to compensate. This will make it less problematic for new locket interaction, as well as cho ult, and other potential things that key off bonus HP.
Locket+stoneplate would still be a strong combo, but not as problematic "must have both if have locket" as it would be with the current +100% HP active.
