Opinion. You may think it takes more skill, but that's just your opinion.
Lol. Look, having that RNG relic proc can mean everything in a PvP. It's the difference between winning a 1v1 and successfully defending your node or losing it. It's the difference between getting that big heal onto a team prolonging an attack. It's the difference in finishing off a target while their healer remains CCed. A system which grants a massive stat boost for 6 seconds which is random is stupid. I also think that adding on demand relics is stupid also, at least in the game as it is today with how much damage classes can rattle off in a few globals.
They need to bring back static stat relics. It was more balanced then and offer a huge advantage over RNG relics mainly because static relics never helped ruin PvP.
