If your trinket is on cooldown and you don't resist/parry/dodge the bash then it is very hard to win against a druid yes(pray for lucky crits), but also if it's 1v1 after everyone else has died then the druid should be out of mana or very close to it which makes things slightly easier. Oh, also, a druid in pvp gear usually has pretty high dodge so I wouldn't waste rage trying to hit any whirlwinds, rather fill in with hamstrings whenever you have spare rage and hope for an overpower opportunity.
