100k dark elixir is way too much for minions research. It costs more than any other dark troop to upgrade (golem 5 is 2nd at 90k) and the gain from it is not much at all, just the usual slight increase as all the other lvls. On top of that, the cost for lvl5 is 40k. Where are they getting the jump to 100k from?

I want minions 6, but it just isn't worth it. I feel like I'm missing something awesome about them to make it worth it, but I'm not.
