Hello, I see many people out there questioning the balance of the game, but it is clear these issues do not exists. The real problem is that you are a bad player, but by following a few easy steps, you can become the best of the best.

Step 1. Find a balance. Obviously night blades and Templars are not under powered, their buggy Passover and abilities are the players fault. By rerolling sorc or dk you will be balanced with the other sorcs and dks. So do that.
2. Find exploi- er... Creative gameplay. Spamming alts is ok, but only if u blame a skill tree that is not at fault, like vamp.
3. Now obviously your lack of reaction, poor planning or bad playing will be the result of your continuous deaths, so scream for a nerf in the wrong field... Like bolt escape.
In conclusion the game/skills/monsters are just fine... l2p
