I would stay combat, but instead for the cookie cutter lvling build try make a build that lets u use swords for faster lvling, low dungeon dps, and daggers for pvp!
on sitting targets ambush is 100% crit anyway.
Maybe something like this:
https://valkyrie-wow.org/armory/tool/ta ... 0000000000-U have all the important cds for faster lvling
- pvp dagger twerked (improved sprint + kick + backstab)
-Pvp hitcap 5%
-no weapon specialisation means no respec when getting new weapons
- missing parry and riposte is a downside for lvling, but u get more dangerous in pvp.
Having a good dagger with adrenaline rush and thistle tea should get enemies down rather quick:-)
