Which would be the fastest levelling solo and at 50 farming for plat ?

My guess is cave shaman would be best since endurance for permasprint while kiting dotted mobs. BA BD can also aoe dot but not run for ever. Supp BD can chainpull but for money making (via salvaging) its mostly quantity over quality. so AE dotting as much green/blue that drop stuff wins i guess.

For leveling, im not sure i guess when you spec your caveshaman for aug first, you will have an edge. solo vs solo im not really sure who wins.

Cave shaman takes much longer to effectively farm with, but will be better once you get setup. You need 22 aug 23 cave for permasprint with LW2, and 2nd level AE DoT. You need to be level 32 in order to have both. A supp BD will be able to chain kill blue/yellow mobs from level 18+ and can use the tailor tradeskill (less cost to level up) whereas shaman can only do AC for trinket (though it isn't incredibly expensive to get to 800). It's preference. Shaman needs gear, LW2 (350 RP), and to level to 32 to have all your toys. BD needs some gear, a staff, and to be 18 for first heal pet.

Awesome , thanks for replies

in beta I was using 41 sub, 34 aug and 8 mend, LW1 was enough for perma sprint with this spec

Both are ok, but BD can start making money faster (around level 35 killing patrolling Drakulvs in Malmo for Jet Bloodletter chain drops).
