I mean, if you can get them from islands quest, sure, but, I was waiting for the 5th or 6th day or whatever hoplites, it takes 35 hoplites to get 5th farm effectively. If you can get them without spending any money, better, they are helpful defensively, and helpful offensively, but you're better with just Sword+Archer defensively, and Slinger+Horseman offensively, but hoplites help I guess, just not a big fan.
