PP2K is hard to block or unblockable depending on latency, she doesn't have to worry about the opponent fuzzy guarding, and can mash out of just about anything.
Tempted to try DoA on XBL some time, but I'd need to buy Kokoro. Heard from a few people that it's not much different, and I've heard from others the competition on XBL is much better.
Well, which character can't mash out of everything online? With PP2K, you are better of holding it immeditatly or just fuzzy after it, so they only can try to throw you. If something isn't dangerous on Phase, it are her lows :>
If they mash, just use a fast counter and you will land stuns all day long.
Playing Phase online is actually very difficult because you can miss good damage due to dropped combos a lot.
