Unleash put a question on the table the instant this hit the battlefield: a 3/3 first striker that couldn't block while it held the counter, or a 2/2 first striker that could. The mechanic packages aggression as an irreversible choice (the counter, once taken, tends to stay, and the can't-block clause rides along with it), so the decision is locked in while the shape of the game is still unknown. First strike sharpens both modes into something a chump cannot trade with profitably: at 3/3 with the counter it dominates the red zone but leaves your own flank exposed, and at 2/2 it still wins exchanges against equal bodies while staying home to guard you. That fork is the whole design. The choice is to read the matchup as it enters and weigh the value of a blocker against an extra point of pressure, then live with the verdict. Most aggressive red creatures hand you that tempo unconditionally; this one charges for it with the option to defend, which is exactly the tension Unleash was built to create.
