Well I don’t dislike playing assassins, but I have some problems when playing them. As a Bruiser main I’m used to a more aggressive playstyle, which sometimes results in a little bit of tunnelvisioning. As a bruiser this isn’t as much of a problem, but when I do something like that as a ranged assassin I oftentimes find myself beeing out of position rather quickly. Which leads me to the second problem I have with them: they are way too squishy. If you are cought out, your done (outside of the intervention of your healer or tank). In addition most of the ranged assassins I like aren’t really good at 1v1 either, which is an aspect of the game I do enjoy a lot.
I do enjoy bruisers far more, because I feel like I am more independent from my team. I can play the macro game and give my team an experience advantage, I can prove my skill by pushing out the enemy laner and in a teamfight I can go ham without beeing too reliant on the other team members.
