the state of diablo 3 - channeling

Let's be honest here, with the way most people play this game.. almost all skills.. are channeled skills.

Why? Because unless you have some of the more interesting builds (based on items).. we're clicking on stuff and holding the button down..

So.. what's the problem with this? Minus the flavor of skill animations.. channeled skills can be directly compared with regular skills simply by the amount of damage that they do and how often on average that you'll stand still

Which is fine.. except for the way itemization works.. because when things are too easy or too hard.. channeling at best feels clunky and at worst just feels bad.. AND it's a lot of trouble to switch your gear out to be optimal for some other skill instead

How to fix the problem? I don't really know if it can be fixed with the mechanics that are currently in the game.. perhaps more damage/utility is good enough to make a difference
