Crafting one yourself is unlikely to be the only way to get one. There are plenty of tier 3 items that come into the player's possession long before the player could craft those items and some are things that player may NEVER be able to craft on their own. I'm trolling a bit but not much. This really is just the first iteration.
Why is it that all the people who are the loudest critics of how TFP always redo and redo and redo features-- all of a sudden are certain that this first implementation is going to be the final implementation? (Now THAT was a troll

)
This is true, I am sure they will expand on the drone. Honestly? can the drone keep up with a vehicle? cuz if not that kinda defeats the purpose of using it as a mobile storage container.
As for why people are critics about that Roland its because the game hasn't really... gone anywhere since a 9 or 10. Yes, we got some new items, graphical updates or poi's ,but hasn't gone much farther. I mean steel has been the final tier for 5+ years, we need something above it several mods do this including new ores to mine etc. My problem is TFP keeps redoing how the game is played and its been going downhill since after a16.4, progression was the best in a16.4, it just needed to be tweaked. Also the stat system does not stop level gating, its even worse now, as perks are gated behind stats, So you have even more gates blocking them. so they went backwards. Wanna use say pistols but had no plans to spec in agi? grats your always crap with them unless you pass the Agi stat gate to get the perk(s). I'd rather it just be a level gate, at least then once you meet the level your free to choose what you want.
TFP basically turned 1 gate into 5, since we now have 5 stats that gate perks, instead of just a level requirement. Check out Darkness Falls, its a good combo of level gating and action skill gating. Like blunt perk, you can get levels of it at 1, 10, 20, 40 then 60 blunt skill, and each 20 skill on the 1's like 21, it adds more to it. Bascially the weapon skills aren't level locked, while stuff like crafting tier IS level locked.
Undead legacy is more vanilla it has the stat system, but, the power of each perk is split 50% from the one from stats and 50% from an action skill for using the item group, so even if you don't get the stat/perks you can at least be 50% more effective with them from just leveling the action skill, you need both however to gain the full effect. This way is best and closest to what TFP has, as at least you can still be somewhat good with a item group without having to invest in the stat. Mind you for full power you need the stat+perk+action skill, but its better than vanilla where its either the perk+stat or nothing.
