I know this isn't a popular topic because it seems half the higher ranked players use ecomanager, but let's face it, we have a tool/macro/script that is saving players inputs so they can focus their attention elsewhere, optimizing mex and engie pausing/restarting to keep the mass and power flowing. To me, this is allowing the computer to play part of the game for someone, thus should be considered an exploit or a cheat.
I know removing ecomanager from play will require players to manually manage their eco again like the rest of us, but at least players of equal rank with one another will be on a level footing again because both will have to focus equal attention and apm resources on eco along with everything else. Higher ranked players will adapt like they always do and continue to kick ass.
RTS games were and have always been about the commander telling their army and economy what to do. Ecomanager removes a layer of this. Yes, there are other tools such as advanced targeting priorities, but I think a solid argument can be made that advanced targeting priorities makes sense as something intended in the spirit of the game, whereas ecomanager is not.
