Do you take scoundrel and sneak? If so how do you utilize your abilities?
1 Scoundrel for Walk in Shadows (take at creation, because it will be a while before you find a vendor who sells the skill book). 2 base Sneak +1 from Cautious trait +2 from gear gets you 5 Sneak.
With the Guerrilla trait, attacking from stealth gives you double damage. Ending your turn in stealth can prevent you from getting attacked.
Do you stealth before a fight and open from stealth?
Depends on the fight. You can open a fight by stealthing and taking a potshot at someone to enter combat, but at later levels that's probably more trouble than it's worth.
Do you restealth during the fight?
Yes; stealth, shoot, repeat until your AP gets low, end turn in stealth if possible. You need to be out of enemies' line-of-sight or stealth will fail.
Are rangers viable without stealth?
Never tried that...I imagine they'd still be ok as long as you keep your weapon up-to-date and use your special arrows wisely. But Guerrilla + Sneak makes their damage much, much better.
How does haste work in general and with rangers specifically
?
Haste gives you extra AP and movement speed per turn in combat, but only for a short while (2-3 turns). Extra AP = more attacks and movement, which is good. Pretty useful at the right time if you don't have Glass Cannon, less useful without it, I guess.
