>>27525998The burn chance of scald is just too good to pass up. Not only can it cripple a physical attacker, it can help wear down just about anything. A handful of mons, like Greninja and offensive Starmie, absolutely need to get OHKOs, for which hydro pump is the best bet.
>>27526056If you're faster and your opponent can OHKO you:
Use the stronger but less accurate move. 80 or 85% chance that you get the KO without losing your mon. Small chance that you lose your mon for nothing.
Use the accurate but weak move: 100% chance that you get some damage in, but your opponent will survive and KO you.
