stealth and sap...
I leveled up sub to about mid 40s. At that point I switched to combat maces for a change in pace. Mid 50s I went back to sub for PvP. At 62 I went mutilate. And now... Im going back to ShS :P
You can level up
any spec you want. It's a matter of preference. Sure combat has steady damage and control, but sub has utilities, and assass has burst. The same goes for weapons, swords/maces/fists have steady damage, daggers allow you to use every (rogue) ability in the game (ambush, BS, mutilate).
Level up whichever tree you think is best, If you dont like it, share with us your problems with it and we'll help, and if we cant, respec.
