I made the mistake of diamonds at first as well, switch to rubies you will be much happier. Since you're not running a punish build and only have 20 percent block on your shield I would roll wrathful instead for the healing throughput and replace hold your ground with finery for 70 str on top of each gem that will already be giving your str if you switch them. Don't forget that STR gives damage reduction as well as dmg itself. You'll kill things much faster if you do those two things. If you have survival problems (which you shouldn't) then you could run law of justice with immovable object instead. Find a 2h weapon with a socket even if it has 200 or 300 dps less (which in honesty you should be able to find one with more dps and a socket) it will increase your dmg immensely with a emerald in it.
As far as the topic post goes I go with this rule of thumb:
T1: DMG 350k+, 4 mil tough
T2: 450k+, 5 to 6 mil tough
T3: 500-600 + elemental mods, 6-7 mil tough
That's as far as I've gotten but Im sitting at 580k dmg, 6 mil tough, 60 percent holy dmg, and T3 is doable but not quick at the moment. I find that at 6 million I'm slightly squishy, but I am running offensive passives. I could sub them for defensive ones and last longer but take longer to kill. I don't die typically with those stats but, I do have to pay attention to things.
