FaZ, any comments on SW? Especially on the hardness of SW, compared to other heavy carries e.g. Arachna, DL, MB, SB. Let's throw in Pesti, SS, and FA too.
SW IMO definitely needs some buffs to match up to the current metagame. Did some reading and play-testing, and I'd definitely say that Deserted needs a buff of sorts. Might be any combination or single buff of does not count creeps, affects creeps, increased damage. Desert Curse could use a rescale to either be a better farming tool or a better ganking tool (small buff on personal MS boost, maybe). Dissipate has a huge bundle of counters, and I think that a slight buff to the magic damage amount could serve him well. Stat boosts, in base damage and base STR, could give him a slightly easier time laning.
Either a variety of small, tiny buffs to SW or a slew of tiny nerfs to the majority of ranged Heroes. 'Cause the game and lineups are pretty much stacked against SW.
Considering all of the crazy animations, MSs, damage, etc. on ranged Heroes, the majority of melee are left behind, as you have said.
EDIT:
I'm really tired right now. I probably said some pretty stupid things that I don't actually want.
Core idea is that SW needs a slightly better early game. Primary focus of buffs on Hero's stats, as opposed to skills. Skill-wise, if we increased the effectiveness of Curse by boosting the MS bonus or decreasing the mana cost, that could work. Maybe, change Deserted such that it's procurement conditions are more lenient, e.g. damage is merely reduced by increase number of enemies, or it does not count creeps, or it deals 5/10/15/20 True when creeps are around and additional +1/3/5/7% if nothing is around (so LVL4 with nothing around, 20 True + 7% of base attack damage, True), or it can work on creeps.
