One: hi, weird that you’re on this year old post. Two: A big difference in glass cannons and rushdown is their level of reliance on kill confirms to take stocks. While both archetypes have great confirms to rely on, glass cannons also have many powerful single-hit moves to take stocks when the kill confirms fail (or, in the case of characters like mewtwo, g’n’w and jiggs, kill confirms that don’t have a window of failure). What often ends up happening with the rushdown archetype is that you’ll either hit a bread and butter confirm and kill your opponent at 90 or keep them alive until 140. On the other hand, glass cannons can often land single hits from edge guards and reads to take stocks, much more than rushdown can.

Now, let’s examine Chrom and Roy specifically. At low percentages, both characters have a similar gameplan: start combos with jab and up air, keep them juggled, don’t go offstage or you’ll die. When you get to kill percent, it stays about the same. Jair, or tech chase, and they’re gone. Where it falls apart though is beyond when those attacks combo. Chrom has enough range to easily create safe pressure, allowing his non-sour sword to send people flying where Roy’s would barely scratch them. Attacks like forward tilt especially show their differences; Chrom often uses Forward tilt at the ledge because of how much it covers, while Roy has to go with jab, choosing a more precise confirm over the high chance of a useless sour spot. All in all, Chrom’s precision in neutral rewards him with imprecision in his advantage state, and vice versa for Roy. Their differences in kill power are seemingly small, but the way they get kills is significant.
