All classes can solo just fine. But those who want an instant cast are just impatient.
If you wanna lvl without touch interupt i got a few tips for ya

Trying using roots when you're lvling at the trees in ow, im certain they don't have ranged attacks so it shouldn't be a problem for you to heal. If you want a lvl 1 touch cannot get interrupted so you can spam that as much as you want. A howling wind build might work for you as well, i remember that build worked really well until 140.
Me having an average of 1.9k heal with a 46 touch is quite good and a 2.1k with a 50 touch with extra ring. I honestly would love to be able heal half of my hp instantly every few seconds. But as pedo griffino said where is the fun in that, we would be so op that everyone wants to be a druid.
As for seeking attention, well we all know that iJoin doesn't seek attention

If you want to know why there is the exact same topic on the druid forum so check that one out please. This post could be considered spam as it is a copy of another so please delete or lock.
Oh and
Ah lvl 110, that was easy for me. You will change ur opinion when ur 175+ trying to solo
