After sleeping on it and trying again today, just wanted to expand (for pve):
F1 interaction with Renewed Justice feels great. Having it reset often makes me feel like the mobility is serviceable, allowing me to reposition the claws or cover area more often with them.
I don't know if it's because I'm 250 ping, but often the F1 doesn't land so no claw. I have to be just outside or in melee range to guarantee it hits. With the cast times, animation lock and ping, I could probably run the short distance in the same amount of time.
I do like the claw for aoe more than Spear of Justice. It would feel better if it appeared instantly like sword 2 symbol. I have to make myself use it often to feel the spec's dynamic, but it's a chore.
The only new utility I use for pve is Whirling Light. If I'm saving virtues for when I need them, I really don't get a lot of new mobility. When I do use virtues for mobility, I have to burn 2 of them to traverse a useful distance.
I also wish the payoff for F1/sword 4/utility/elite was explosive. I wouldn't want them all to have mobility if it means each individual one needs to be throttled. Dragonhunter traps feel great with mobility because it's a big payoff for less risk/investment.
At the moment Willbender feels like you're going nowhere fast. You have to put yourself out to do something that core/DH/FB does easier/better. I hope this feedback helps.
