I think all adequate people understand that we need this item in our game because it's impossible normal play by engineers without it. During the leveling drone needs some equip and after 50 lvl it needs other items.
Or may be developers will do patch with drone's attributes retrain when done character's attribute retrain.
And it will be good if attribute retrainers gived together with skill retrainers for quests because the same problem is for characters too.
Thanks for attention.
