assuming both chars are same at level and gear, and players with same skills - warrior/rogue will win. but that doesn't happen all too often so u'll have to analyse ur own situation here.
as a guideline however, since u mention that ur friend can only pwn newbs, i doubt he's a very good warrior/rogue. as a warrior/cleric here's a few tips and tricks in order to beat warrior/rogues:
- if bless and skins are allowed, always have one or the other on though preferably bless since skins won't allow u to switch to cleric without losing the buff
- if u can get a good set then go robes for mp reduction, otherwise go light armor and get the passives
- when knocked down, i rather use cleric rod than 1h as ur heals will be more effective PLUS ur passive def goes up.
- always try to bind and dull until they have one or the other or BOTH
- soften them with the kd -> triple swings during bind/dull for extra damage
- u should be able to finish with a sudden twist (if stun or bleed proc) -> daredevil -> turn rising blah blah and if not just rinse and repeat the above step
- if u find urself down and still alive after his DD -> mortal wounds...ALWAYS spring assault and shield crush in this order to prevent his follow up prick/butterfly
keep in mind u'll also need to be quite capable of switching and keeping urself in a healthy state using healing cycles so practice is important!
and remember to use grains to reduce delay
good luck.
, but i wanna use a warrior/cleric or a warrior/rogue to fight him
