At low levels yes a thm is going to make you look a bit weak but just wait till you're high level. In situations where that thm/blm is nothing but a dead smear under a mob you will be amazing. You'll pop invigorate, whizz in to stun your foe with shoulder tackle allowing you to wheel around him pulling off your combos the you'll see him miss as your featherfoot procs, you stun him with haymaker and then can hit him with yet another devastating combo. Monk is awesome, stick with it and you'll love the job.
