Again with the Stormtrooper Ewok thing- gawd.
ANH: easily wipe out/ capture the defenders of the Tantive IV, who fall like flies.
ANH: Kenobi, who should know these things, having ordered Republic clones around in the clone wars (in case your forgot, stormies are clones): "only Imperial Stormtroopers are so precise"
ESB: Hoth: the snowtroopers kick Rebel ass- sweep aside the rebel defending force: "Imperial troops have entered the base; Imperial troops have **static**"
ROTJ: at least two sniper shots from stormies- one was definitely going for R2, the other was a shot on Leia.
Ah, but the stormies lost the fight at Endor! Ask yourself, would the Rebels have one if Chewie hadn't comandeered an AT-ST? Of course not. There would've been at least two AT-STs annihilating Ewoks and rebel commandos unhindered if that had not happened, not to mention the stormies would still have their fire support. Ewoks also have homeground advantage, and while looking very cute nevertheless are pretty damn strong. I wouldn't want one to hit me over the head with a club.
As to their supposed inaccuracy: two words: charachter shields. Except when they're firing on the heroes, the kick ass
