I don't consider removing a needless upgrade to be lazy balancing because I don't see any purpose the upgrade serves beyond making Aeon stronger in their strongest game segment. I already suggested that if any faction needs the increased range utility it would be Cybran. Lazy balancing would be equalizing aurora to every other tank rather than something like the lab/blaze change which gives Aeon an out for a weakness they have in a unique way.
If no one can name a weakness in Aeon that gun range is there for, it's just there just because it is. At which point, just give it to Cybran anyway.
