This is my armory if that helps you

I won't do Fal'inrush cause i prefer the extra haste over the extra arp ( since with the bis list the haste drops a lot ), i keep using the shrapnel star
You need to remember how everything falls in place
Haste gives = More possible hits
Hit gives = More white dmg, more poison procs, more dmg cause hit chance increases crit chance if you think of it
Arp gives = More dmg since the first two criteria is on good level
So try to keep a combination like around 850-900 haste, arp as much as you can get as long and you don't drop haste too much, hit as much as you can without dropping the first two criteria.
So if you have haste over 840 minimum with that bis gear don't switch trinkets, haste trinket will give you more possible hits than the extra hit from mote of anger but it will get serious handicapped by the immense loss of hit
