It is just another adjustment thrown to us Rangers.
The big suprise from Dracoboars is took until level 65 to find this out. The first mob I hit in my early 50's for double damage, 110pts, I thought, Wow! Great! By the second mob, I realize, well, I get one shot off, and hopefully do not miss.
By 55, I am using snare, root, and trueshot only on very select Mobs. I use it for preventing damage to me with Mobs that hit very fast. The slower hitting, big damage mobs (150-200's) I seem to do okay with in melee, and drop in 1-3 minutes. It is the fast hitting mobs that I stay away from until trueshot recycles; yes, the fight lasts several minutes, but that allows my health to regen.
We are not a slay everything in sight class as others may be. Know the zone, map the mobs; select the fight, and have exit strategy and multiple pull strategy.
Play a 'Ranger'.
And the lesson is play it now - do not wait until level 65 with a bunch of AA's. Solo, group, explore. Find the Ranger niche, find the Ranger limits, and adjust. My toon is awesome when played as such - for me.
