When you switch jobs do you have enough points for everything in your action bar?
I think that happened to me once when I switched to conjurer from thau.
Just make a macro to switch jobs and populate your action bars as you see fit per job class. Easiest way
Ooooh maybe not, I had assumed what SE meant was if I have 5 skills on conjurer then go to lancer and set that up. The moment I got back to conjurer I have those conjurer skills back on my bar I used before... unless that's wishful thinking >.>
Not sure it works like that, when I switched to Con from Thau Thau was rank 8 and con was 1.. and I was able to "put" a bunch of con spells on my bar (think because of all the lag early - this was D2 and I was in the CE group)
Anyhow all the Conj except like 2 disappeared...
I'd recommend to just make a macro to swap item and do the first 9 spells of your action bar (since macros have 10 lines) save you tons of time in the long run so you aren't swapping your bars around each time you change a class.
