When using mining drones in combination with a goblin (for lazy protection) I happened to stumble over some old restrictions:
As you can see the game does not allow me to move 2 different types of drones into 1 group.
I wanted to create a group of 4 miners and 1 goblin. It did not let me do so.
However, you can start any mix of drones.
… and you can use them as intended.
Using the ‘attack’ prompt on an asteroid the 4 miners rush away while the goblin remains near my barge, guarding it from NPC threats.
You can:
- launch mixed groups
- use the mixed groups
- they operate to the best of their ability in mixed groups (mine, shoot, heal, damp, etc)
You can’t:
- create mixed groups
Since this is the case since day 1 of Eve, this might was done this way because of limitations at the time (or other design reasoning), and until today no one bothered to look into it.
I think this should get another round of consideration, allowing every player to group and mix however he thinks it works best, making handling of drones of all sorts easier. This will help basically any kind of player ranging from miners, PvE, to PvP, as well as starters that simply use what they found…
PvP players will most likely be the ones gaining the most but it is more a quality of life than a direct increase of their output. (they still can make 2,2,3,3 drone groups and start those in pairs mind you).
I imagine everyone likes having fewer restrictions in Eve and the way its played, including something as simple as drone grouping
