Several times I was running into the problem of having not enough skills to proc my devotions - and at the same time binding devotions to the STANDARD ATTACK could have solved that.
Plain & simple: Actually why can we not bind devotions to a standard attack…?
My guess is because they need an active skill to proc off of and standard attack isn’t classed as an active skill.
Right. But since this is the ideas & feedback section; I kind of propose to transform the standard attack into an active skill.
Not bad idea,but ABB with Venomblade will be even more powerful,if empty attacks trigger devotions. 
Would only be more powerfull if that abb build were out of triggering skills otherwise.
You can bind devo procs “on attack” to WPS, and WPS are not active skills
Right. Even that´s possible. But not standard attack…
Unfortunately not every build has wps, I always have a lot of trooble where bind devotion procs playing some casters like PRM or FoI. It’s quite sad that game forses some builds pick skills on 1 point for only binding devotion when other ones don’t suffer from this problem/
Seriously, why so much favouritism for weapon damage builds here? Devotion proc placing is the lesser advantage compair to flat damage and ADcTH only affectin WD.
