Lvl 40 where to go?

[Triiz]

I tried to level an alt in COM groups through the low 40's a few weeks ago. The xp at 41 felt as slow, if not slower, than level 59 for my main. It was easy to get a group but that was the only positive. It's mind blowing to me why it's so popular, I would do anything but that unless you really want to drag out your 40's.
