Twelvesky2: Make it posable to buy (X) amount of energy at stations with cry, say 500e for 100c and a faster spawn E Cell spawn rate. So many of the E cell fields have mobs/rats mixed in so you spend almost all of the e that you have farmed fighting mobs/rats making it take almost 10 times as long as it would have in the first place.
Cell recharge value grows with level of area it spawns, it takes approximately 40 charges to get your ship full, if you are on level(twelvesky2 gold ) 7 and vega 1, or level 14 and vega 4, it's same, of course you need also to buy better collector for higher level areas, so your gathering speed will not decrease + buying energy for crystal at 5/1 rate sounds reasonable - it was already suggested on developers site.
Cells spawns fast enough, even on basic areas many fields can be safely occupied by 10 people and this is not kind of game(Twelvesky2 powerleveling). We imagine to see 50 people in one place, there is a reason, why those areas are dangerous, they recharge more, than safe areas, but anyway, there are just few mobs, you can easily avoid them, of course you need to watch your radar.
