Using your mouse and rolling over the party screen is kind of bad

cause u watch the red going down...
I'm used to 1st person shooters so I am way faster with my mouse and the 1-8(weapon select) buttons then any other combination...
I use the standard 1-8 default and tried the 1234qwer combintation... but its hard to get used to something else...
Just get a good skill setup, get important skills on buttons ure on nearly all the time and the less important on other buttons (for example I always get Return/Dark Escape/Hex Breaker/Channeling etc. on number 8)
Most important about infusing is the enviorement... and radar, radar is very important... watch the movement of the enemies and which way they face... Especially on fake spikes its important, Gaze 1 Spike 2, when they starting to face some1 else...
And like every1 else says: practise, cant argue with that...
