Trials of Osiris is very competitive, which is why people love it. Some do it for fun, others do it to go flawless. Of course some weapons are overpowered, like Thorn. I recently played trials today, ran into two teams with all thorns. The fact that the weapon burns overtime, you have a higher chance of dying. Now how is anyone supposed to escape three thorns, it last three times than the burn would normally last. I personally think that if thorn is going to be continued to be used in trials, it should be limited to only one thorn on each team.
