I as a ranger would love to be able to disengage if I'm losing a fight. To get stealth as a ranger, have to land hunters shot (forcing you to use LB), use smokescale and have it out / wait for it to finish making the field / leap into it, or run porcine and play roulette. Also Ranger has essentially one block on GS, and sustain either means losing all damage or having basically two skills (dolyak and rampage as one / SoTP).
But yes, please keep complaining about LB 2. At least in this case the devs saw ranger is in probably the best place it's going to be until the expansion so they left it alone.
Just my two cents, but Prelude Lash can be run without signet of stone--just have to time it and be good at kiting (which as a Ranger is probably a must anyway). For the topic at hand, swappable F3's would be nice so that it's not such a chore trying to find the correct pet / archetype combo.
