thanks for the tips missroadkill, very nice, i had some fun trying out the different stats but mostly i got nowhere... tried changing purple abilites and although it says they have changed they haven't - managed to get it to say +500% hp on my shield
also tried removing the skill cooldown but although i can keep firing the skill without delay it doesn't do any damage just animates...
but i did manage to remove the pot cooldown (think i changed it to 0.2secs - good enough for me)

but failed completely trying to make adren pots more effective
anyway i don't play RF anymore but messing with the files is not something i'd recommend - i had no idea what i was doing and the decryptor was pretty unclear but if u make lots backups u'll be fine.... i hope :P
maybe someone else can confirm this method can actually change more then just recharge times?
