User blog comment:Waddle3195/BTD5: Path 1 vs. Path2/@comment-3153244-20120407143731

One thing is, the Path 1 upgrades are powerful, but the Path 2 upgrades' ability makes up for the power. However, the ability needs recharge time, which probably means that a variety of towers is best. I still think that Monkey Temple is a lot stronger than Terror (if you know how to use it!)
