This may or may not have already been mentioned but here is something that, IMO, is essential at some point. And it would add SO much to the game.
Currently, there is no need for a resurrection line of nanos. We have cell-scanners. The intent/purpose (out-of-character) is to save experience. Well, what do you think of creating a line of nanos that does remote/uplink cell-scanning? Basically this line would perform the function of cell-scanning (saving experience) in the field. The percentage of experience saved would never be 100% like the stationary cell scanners in town, but would scale with level. For example, the first one might save 15 or 20% of the experience made since the last scan (in field or otherwise... i.e. town). And it should only be allowed to be cast maybe once per realtime hour. There should be single-target and team versions. The nano would also require cell-scanner uplink equipment, similar to portable surgery clinics. Now, this is where it gets touchy. In my opinion, this nano should be in the engineer's arsenal and perhaps, maybe also the doctor's. The nano should not only require appropriate nano skills, but also a very high
amount of engineering skill, which is why I would say this line suits engineers best.
Just think of how group-friendly this would NOW make the engineer. I know I'm sold and I don't even play an engineer, heh.
Please consider the idea.
