Hiked to Climber's Camp on July 10, summited + hiked out on July 11.
Our group did not need ice axe or crampons/microspikes. We did not have to travel on snow, and I was able to do the whole thing in hiking shoes.
Rockfalls were definitely a concern. At one point, our group saw a basketball-sized rock come tumbling down. Luckily Friday was not too busy (3 groups / 8 people including us). On our way out, we saw a lot more people hiking in to Climber's Camp for a Saturday summit attempt. Be safe out there, especially on a busy day.
The creek crossing on the north side of Lena Lake wasn't too bad. There were lots of fallen logs on the trail; none of them were impassable, but annoying to duck under or hop over.
Route-finding was not bad for the most part as the trail was fairly obvious and/or marked with ribbons (thank you WTA). It got a bit trickier above the tree line, but the cairns helped.
