Guild Wars 2

if u want to change off hand attunement,u must add a added button such as ,f5(u can change it),means
touch f5 then touch f1 u can change offhand attunement,to fire
if u want to change mainhand attunement u don’t need to do it,just touch f1 then your mainhand attunement is fire

or else u can set up same time touch the The mouse wheel and f1-f4
this method is better

or this method ,add gocam,so we can use right button of the mouse easier a&b button change attunement
or else add one button on-off,if u off just touch f1 u will make offhand fire,if u then want to change water ,u can touch f2 no need touch anybuttone before ,and then if u want to change offhand earth u can touch f4,and no need touch anybutton before,if u want to change mainhand fire u can first use the button u selcted “on-off”then u can choose mainhand attunement,this is best methord
