Yus I'm pretty sure the 65 bracket is more active and has more variety, of course. ;o
Well i went there with me mystic to see how was everything now,and i saw a lot of rangers/avengers/eles,reminds me a bit of when i left it with my sin due to extreme xenoa annoying complex.so yeah maybe ppl go for the most kills and not teamwork.
Could be fun when i have my mystic at 65(hes 60) can make him 65 easily,the TB combo wand+shield is another story,but for a lvl60 mystic i had a nice survability with no resists whatsoever so im guessing things can get more fun when i have everything ready.
