What is th e good use of Golem?

I have this Golem(Lv1) for quite sometime, still have no idea how to take good advantage of it/
high hitpoint, that is good; Speed 12, it is OK; however, damage is too low compared to other powerful super troops.
Also, 30 space required, a little bit too needy.
Mow, I prefer my Lv 3 PEKKA in the raid.
Do i have to upgrade Golem to LV 3 or 4 to get some real power? or Use it as a shield for other troops?

Its meant as a tank troop. You use it GoWiPe for tank, while the pekka does damage, and the wizards do damage from behind.

Use it as a Tank. Be careful, Inferno Towers can make short work out of your golem.

its a man shield so to say :D hehe there is no real way to use them but in front of other troops are always the best way
