Specialist machine versions added to each tier above prototype aside from current weapon pack variants would be nice.
For example hunters could get a version with better sensors added to the group that can call extra machines or track you significantly better if you don’t disable the sensor pod and antenna.
For runners(and hunter imo) i think they need to add up armored or fully armored versions , maybe even give them a dedicated melee role and have the unarmored ones do the jank charge attack less.
They could add harvesters that are modified to carry repair feature from wolves ,variants that are uparmored and comparable to tanks and have mode defense around their weapoins and potentially upgunned. An interesting support variant could be runner and harvesters that use flares to temp disable powered scopes or interfere with soviet machines and flashbangs for players
Soviet machines definitely need a heavy hitter of some kind because their current machines do have much better DPS then swedish ones are also much weaker(firebird is especially a joke if u got an MG with extended mag) so a tank variant is needed for em but i think the lynx squad compositions are something that can be used as an example of how to buff swedish machine squads.
