Coming back to gw2, looking to make a thief.
It plays fine?
Depends on your personal preference and what game modes you want to play as there are many variable builds that can be effective now. Both HoT and non-HoT builds are viable.
D/D (condi), P/D (condi), D/P (power), staff (power HoT only), sword/p (hybrid) are some of your options.
