Probably. The T3 issue was a little lax in kill speed coupled with taking too much damage for my sustain at the time so it had a few unnecessary deaths which slowed the run down. Granted, I've since added like 2k Armor / 300 AR so I might have fixed the problem already.
The other day i was rifting on T1 with 2 wiz and 1 wd and they just melted everything. Elites dead in 5 seconds.
I was doing nothing, NOTHING, just walking around trying to hit something. Very frustrating and needless to say i was playing on a crusader.
What's your build? Gear level compared to them? I group pretty regularly with basically every class and I never feel useless. My damage is pretty good all things considered. The problem is it's all burst. Once I unload Condemn and FoH's, I'm doing little compared to the Wizards or WD or DHs. But that initial burst? Probably higher than theirs (if I preload the Condemn, it's ~65M Average Damage in the ~1.5s it takes to triple FoH). The Crusader problem is the time to refill after a full wrath dump is too long.
Honestly, Heavenly Strength just needs to steal the Spirit Generation passive that 2H Monks get from The Guardian's Path. Or make Provoke a bit better / Zealous Glare partially built into Shield Glare. Going to test how I feel with a 1H build but from what I did yesterday, I have too much Wrath.
