Ranger in wvw/leveling?
Levelling is fine once you pick up a reasonable selection of pets (including a brown bear) and a few basic tricks like in-combat pet swaps and pet control. Most of the time me and my bear can take on 4-5 mobs at equal level, which is 32 atm.
WvW rangers seem to be ok with the right build, from what I’ve read. It’s a question of getting enough survivability, and you’ll probably end up carrying different weapon sets for different situations – I level with Short Bow / Axe & Warhorn, where the bow is great for normal kiting and I can go to the Warhorn for group events, while for pvp you might want to major axe & Warhorn and carry a Greatsword as a defensive second.
Dungeons seem to be where the problems start, you need to be good at pet control even at the start, and some encounters will instakill your pet, causing a drop in damage. There are a few posts on the forums about it.
Rangers are fun in wvw if they suit your playstyle.
In pve for levelling my alt ranger I take sword/horn and sb. Get a bear or two for multiple mob tanking, otherwise use whatever suits you best.
In wvw I run LB/SB most of the time as I find I am most useful with these without ending up dead in the midst of all that aoe, but also carry sword/horn/gs for moving about the map- and those birdies are quite fun when you run into some other soloist. Horn 5, charr racial skill horn 4, qz on sb, your choice of elite and they tend to be running away almost dead and bleeding out their ears. Or blast them from range with LB 3,2 , switch to sb 2,4,5 switch back to LB when 3 and 2 cooled down running might stacking stuff and you might enjoy it, together with appropriate pet of your choice.
