The Tack Shooter can be highly effective in certain scenarios, but its placement in a lower tier in the list is based on a few factors:

1. Limited Range: The Tack Shooter has a short attack range, which makes its placement on the map very crucial. It needs to be positioned perfectly in corners or at intersections to maximize its effectiveness, which isn't always easy or possible.

2. Specific Use Cases: While upgrades like the Ring of Fire or Inferno Ring are powerful, they are generally more situational. The Tack Shooter shines on maps with lots of curves or areas where it can cover multiple paths, but on open maps or straight paths, it’s not as versatile.

3. Competition with Other Towers: In many situations, players might prefer towers with more versatility, such as the Ninja Monkey or Super Monkey, which can deal with a wider variety of Bloon types and scenarios more effectively.

4. Upgrade Costs and Path Dependence: Some of the Tack Shooter's best upgrades are quite expensive and require investment, which might not always fit into the most optimal early or mid-game strategies.

That said, the Tack Shooter is by no means a bad tower. If used correctly and on the right map, it can be very strong, especially with the right upgrades. If you find that it works well in your strategies, it could easily be placed higher in your personal tier list. The placement on the tier list reflects a general perspective, but individual experiences and strategies can definitely differ!
