Hey, I am a little bit annoyed by moving stuff around on between different characters. The easy solution is to put stuff in shared inventory slots. The big question is: How many should you get?
Currently I have four slots filled with three infinte salvage kits and a lounge pass. I can think of other items like the Birthday Cake, Position Rewinder or the White Mantle Portal Device.
I am curious what you keep in your shared slots.
I mostly play one character too, but I think I would switch around more, if moving stuff between characters would not be that annoying.
I have birthday boosters running on my characters all the time and regularly refresh them from the stack in my bank.
