L2 + R2 = third cross bar

[Wildsprite]

And this is why I wish they would have used a controller setup more like Tera's instead of what they have now. It's utterly useless.

Hold down nothing (OMG what a concept!) for the first setup.
Hold R1 for the second.
Hold L1 for the third.

Three full customized setups should be enough for every job. Add in separate crossbars (like I have to do now because have to switch is a pain in the ***) if you need them. They really screwed the pooch on this.

slight problem with this, the controller already does things without pressing any triggers, d-pad(crosspad to some of you) selects things on your screen. and the buttons also do things like auto attack, jump, bring up map, back

your idea is nice but it wouldnt work unless another button was used to allow those functions
