This is one thing which I would really like to see implemented. Back in the day we had the custom formation tool, but that was disabled as it was rather experimental and didn't exactly work well - however I use a mod to re-enable it, because I believe it can be useful in some (rare!) situations. If it was more comprehensive it would be useful in quite a lot of situations. One key thing I would like to see is the option for a 'cluster' formation. You can do this right now by selection one unit, assigning it a recall number, getting all other units to 'assist' that unit, and then you can effectively recall that group of units by just selection that one unit. This is great for forming a smlal cluster of Dox or boombots and can be effective, I think (for squeezing past narrow land formations or avoiding point defence). But it is fiddly to achieve, and when the unit you assigned the number to is destroyed, you lose the whole thing. It would be lovely if we could select a group of units as normal and easily select a pre-set formation for them (e.g. a 'V' for air units, a cluster, a line, or a crescent/semi-circle). These all have their uses, and it would an extra level of depth/micro to the game. I find it quite frustrating knowing that a group of units could be more effective if you could only arrange them in a nice formation before utilising them. Going back to the old, disabled custom formations feature - the main thing wrongf with it, I think, is that the custom formation is not remembered when you make the units move. So you can move them into a nice crescent shape or whatever, but as soon as they march forward, the formation is lost. Annoying. I'd love confirmation that Uber intend to pick up work on this feature again, and work on formations in general.
