One major difference is that since speed is no longer a comparative stat between the combatants, but rather a stat that reduces move cooldown, it is less important to max it out with common opponents' speeds in mind. Moves have a minimum cooldown, so for instance there is entirely no point in increasing your speed beyond the point at which all your moves have already reached their minimum cooldown. Investing in HP is more relevant now even for sweepers who would have traditionally focused on outspeeding opponents.
