What is the attacker's benefit over just sending packets directly to the target with forged source addresses ? Reflection attacks give a benefit for the attacker when the reflection provides some kind of amplification. One example is broadcast ping in a LAN : one single request packet triggers many reply packets. Another example is DNS amplification : a small DNS request triggers a much bigger DNS reply. But TCP RST attack does not provide any amplification, as one SYN packet triggers one RST packet of similar length.
