I am hesitating to upgrade my dark barrack to get the golem. Eventually, i will do it but not now as i have other upgrading priorities. I wonder what is the benefit of golem vs giant (level 5). I know both units are used tank. A golem has (4500/30) = 150 HP per housing space. A lvl 5 giant has: (670/5) = 134, which is a bit less but can be compensated by the higher DPS of a giant. The main drawback of a golem is the huge cost of dark elixir, so I wonder why are people using golem?
Thank you for any advice.
