Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
When I open teambuilder, it says that in order to use HP Ice, my SPEED IV has to go down. I know that it wasn't like that last gen, so is this a new game mechanic in fifth gen, or a bug?
A possible IV combo for HP Ice is 31/31/31/31/31/30. The teambuilder probably only lowers the Speed IV cause that only changes 1 IV as compared to the 2 IVs for 31/30/30/31/31/31
