First and foremost I apologize for my comment before, I'd thought it would be enough of a counter-argument by listing some very obvious friendly fire examples that would sure to deter simpler men. As simpler men could make the connection between the almost "retard" level of micro necessary to get Syncronauts killed by your own forces from the absolutely tiny amount of AOE dealt by units such as the Knightframe, to the retarded level of micro needed to deploy a Desolator in your own forces; but I digress. The issue still stands as it is. Part of your argument is still reasonable. Friendly fire is an issue that plagues not only Foehn but other factions with drastically more damaging area of effect. Though, I'll have to disagree that it's bad game design to have the friendly fire option enabled, as it is a simple fact of life. One cannot control radiation and tell it to only hurt the Conscripts wearing blue, nor can one explain to an EMP how not to effect friendly tanks.
As the Commander, especially in the CnC series, one has a certain amount of responsibility that must be kept in order to ensure victory. In game terms, we would call that Macro and Mirco. One of which, I'm not so sure you understand completely. Mirco is the act of managing little movements such as move, halt, and attack. Thus, each move, each kill, each death is inevitably contributed to the Commander in charge of the operation. In real world terms, we call that responsibility. Now if a Commander understands his troops enough to propose a drastic change in one unit battle philosophy, but cannot, or will not, claim responsibility for attacking a structure when he knew that the ensuing assault would purposely end some of his unit's own lives; we would call those commanders incompetent.
The units and abilities I have compiled into an easy to digest list all share a similar quality. Their friendly fire capabilities are also completely avoidable using proper micro. The Syncronaut situation is very similar to say, Siegfried's cannon splashing onto the EA's own infantry battalions due to a Blotick trap triggering his auto fire. THOSE units/abilities' situation is one and the same as THIS (not these because the Syncronaut is, unfortunately for your case, one type of unit) unit. They all are prone to friendly fire one way or another. I don't see this as "troll"-ing the user, as trolling would probably be removing Foehn altogether. No, the Syncronaut situation is a problem that can be solved (just like all other units I have listed) through proper micromanagement.
The fact that Syncronauts are expensive is a very peculiar thing to bring up. Especially in the topic of unit actions and interactions, not the Foehn economy. I agree that having to spend large sums of money for a permeant target painter is absolutely beautiful. Still, the only thing I can offer you is my most sincere condolences for being a Haihead player in a patch like this. How you must be crying your heart out with the ineffective costs.
Please, if you have any, and I mean ANY, concerns, comments, or other brilliant suggestions, simply reply to me. I do fear, however, that your burns would prevent you from doing just so.
