What are the most important things to beat in the 100 base speed tier? I'm messing around with Manaphy but I'm torn between maxing speed and maxing HP. I find without EV investment in HP, she gets 2HKO'd by basically any attacker that's not relying completely on Water, Fire or Ice attackers (which is, like, nothing). I'm wondering if she really does need to have maxed speed or if she could split it to beat certain things, but since there's no OU analysis for her I'm having trouble figuring it out.
