Guild Wars 2

sPvP is more about capturing and holding a point, with little emphasis on the PvP side itself.

Being forced to change your game play completely to stop an enemy from capturing a point is not enjoyable for me. (yes I know you have to adapt and fight under X circumstances) but the fact you are unable to utilize your class to its maximum potential due to this slack setup pushes me away from sPvP completely.

I prefer WvW small fights or just roaming solo. Because there are no restrictions and I am not forced to play my class the opposite way I fell it is designed.

Generally? In WvW they are the best class for roaming, as intended. Have the ability to disengage when a fight turns sour and a well played thief can be close to impossible to kill while still having the ability to deal out immense single target damage.

They are not the best in zerg fights due to low hp pool lack of AoE and sustain. They excel at picking off unsuspecting squishy targets and low HP runners, however their main strength is roaming and generally punish other classes for roaming solo with few exceptions.

However sPvP is a different story, they are somewhat lacking there as being able to disengage isn’t a very important factor like it is in WvW, its more bunkering and holding a position and being able to capture the point quickly, however they do have some advantages and stealth does bring a lot of benefits to the table so they aren’t really bad.
