Prep has become a "super stance" sort of. Your proto-typical stance had only a few options, but all the options were generally stronger than move available from neutral (kinda like SE now) which balanced against the restricted options and limited movement.
Prep's has two attacks that are available from mid (and none of the moves from it are absurdly strong), but can now duck highs, retreat, aGI mids, while having 3 options from prep that allow re-entry.
Its definately more spammy for pressure, but less brain-dead spam because the moves arn't as dirty overpowered. I think more ignorant people will whine about SC5 prep rushdown than SC4 prep, while raph mains are going to miss the threat of prepA and SEA B's ability to CH for 55 damage for those who step-attack against Raph.
O well it's a different game so maybe it'll be easier to cope.
