About light vs. wind: depends what is easier for You :) Since i learned wind rotation i can give much more dps than on light, but i played light maybe for 4 days vs 4 months on wind. Wind is much more easier for me, but IMO its glass cannon, 1 block (0.5s), 1 stun, 1 KD, vs many skills on light. Light can also give fine dps, if you learn it.
I have problem with soul badges, theres not much info in google aboud soul badges and effects. :/ in all trees theres no archers ;/
