a warrior-survivor combo would be easier on the first BD tour, i think as that's what most experienced BD gamers would advise. that way, u won't run out of ammo just in case your health almost give out. so bows & swords would be best for u. only when u are more comfortable with the game system & the difficulty, then u can try out the mage-warrior combo.
for my case, i started with the same combo as yours. may i know your point distribution & what level u are in? i'm sure it's still not too late though things will be quite tough for now as u are building up your characters.
is the replenishment rate of both health & mana so slow? last i recall it wasn't but then maybe because i played it in lower difficulty level.
one advice i can give u for now is to try hit-and-run tactics, which u can try hit an enemy at long range then u run then go to sneak mode to lose them. do that a few times & i think u will get the hang of this guerilla style. early part of gaming is often hard, as far as i know. maybe i am such a lousy gamer. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
