Ask some polls.
Here are some of mines.
Which do you believe to be the greatest handicap that increases game success?
Caretaker : Increases building success 'rate' faster than units constructed.
Commanders : Do you believe commanders should be ruling instead of doing the units job which is to conquer/destroy?
Other : Personally I think that all zero-k units except the caretaker is a non-handicap support.
What are the balances do you believe should be seen in Zero-K?
Source changes : for example, only the engineer commander can have access to the caretakers.
Stat changes : Do you believe that units should be with certain limits or without to a certain field.
Other : Personally I think that unbalance is also balanced, there aren't any errors/flaws in the units except measurement value scales such as exact size being the value of how much a unit is worth.
