SR isn’t a boss character it’s a all round scout V2 that can does ET wonders.
I have to let you know a Full invested fletcher mergen can only get no 3-4 (well at least can net you a cube) most of the time on wb wars.
Well due to inflated combos. Any boss these day with a miko will enable ALL Meele casters to win the cube.
That include murm shinobis.
the ranger 2 thing I wont argue b/c in true tos forum fashion people are just gonna counter anything I type on that, all I can say is I personally solod every single quest in the game minus 2, the mega boss fights in alembic caves and zima suecourt, cloaking is 1 of the greatest abilities in the archer tree, it makes life extremely easy, trading that for an extra 5% on steady aim is crazy to me, but again aslong as you get archer2 in there its technically optional at that point based on taste
Pretty much like what i say R2 for a stronger 5% burst if you like or scout cloaking for mobility + ease of life.
Investment cost for defense will get you through scout is more for fast pace map clearance of solo objective.
Still ultimately depends on how much one person is willing to sink to the toon and what are you aiming for.

dont be scared by the bickering, unicorn is a very exp’d / high level player, you are safe to follow their advice on the forums, they are 1 of the few people on here that actually have the stuff they comment on in-game
we just disagree on ranger2 vs scout1 is all, you have a well informed decison now though, you can simply pick which will suit you best
you have to be cautious on the forums b/c alot of what you will find is theory crafted by people who never made it past lv220 b/c they have the attention span of a 12yr old on Ritalin
that depends if you can achive 90% crit rate worth of gear or not, then imo i could work
look at the recent wugushi buffs on KR, might be an option to go wugushi 3, seems potent and ranger in general is pretty lacklucker except for steady aim. But thats only one skill.
IMO I preferred scout 
and I’ll tell you why.
imagine you are dying of poison EX. Solmiki 24th floor. Just barrel away and block all poison.To me Scout offers more than just cloaking. So for me Scout 1 <3
