I think all support items should have adaptive regen stats instead of locked stats.
I think its very important that we don't lock Relic Shield to HP regen or Spellthief's to MP regen. Rather than create even more support items, I think we should just give all support items adaptive regeneration stats based on either missing mana/health and/or if you're playing a tank that needs health more.
Sometimes AP supports will take Relic Shield based on the matchup and the very rare occassion where Tank supports take Spellthief's or Spectral. I just think Spellthief's shouldn't be the go to option 100% of the time cause if the changes on PBE go through that's where we'll end up.
