Servers with good ping are insanely hard to find in this region. I've been dealing with 200+ ping here. That said, I actually love fighting 2 handers, as do others. OP, try my style for a while; may help. And personally, I'm beginning to like the 2handed is OP view, because it encourages more people to use them. Not a lot of vets on the servers I play who know enough to do more than sidestep bolts as I fire.
Firstly, I get three crossbows. If possible, the third crossbow (slot number 3) will be the strongest. Then I get the strongest bolts I can.
Next, I stand where I have a nice clear view, with any luck, only one/two paths leading towards me, and they'll have to approach on level ground.
I fire one shot at them without aiming overmuch. They'll sidestep, that is VERY natural. I switch to the second crossbow. I shoot again. They either sidestep or not. But since at this point having a third crossbow means gimping yourself melee (Trying to beat them back with my fists is ridiculous, yet I had to do it a lot of times. Mixture of kick and punch, and a lot of RUN UNTIL I FIND A CORPSE WITH MELEE WEAPONS).....
You know, when you fire two crossbow bolts at someone from two different crossbows, and begin reloading, they don't expect you to finish reloading in time. Usually around now, their 2hand begins to chamber as they get close.
And usually around now, I whip out my third crossbow halfway, and get in a free shot. Note: The fact that aiming must be damn lucky and good is the main reason they have to approach from level ground, aiming high/low quickly is beyond me.
And when I run out of bolts? Go around, find dead body, take weapon. If you die, repeat the shooting.
Note: They usually do wise up to your tactics after some time, but even then, evading 3 crossbow bolts in rapid succession is kinda iffy. Tends to make them go OH ****, at least, on the server I play.
