I enjoy playing power reaper, and was able to solo queue my way into platinum 2 this season with it. And while power reaper was never top of the meta, you could do well with it, and could compete.
But nowadays it's so pointless. Holosmith does way better damage than reaper while having better survivability, better mobility, and better CC. Spellbreaker despite only having T1 bursts can still F1 people as hard as a full channel of Soul Spiral does, while having 5 times the survivability of reaper and way better mobility. Mirage applies 15 stacks of confusion just by sneezing, while being able to run circles around reaper. Rangers now have pets that hit harder than gravedigger. Thieves just dunk on reaper regardless of if they are daredevil or deadeye.
Reaper needs serious buffs in damage if it's going to be competitive in the new meta. And by damage buffs I don't mean adding more ferocity to Reaper's onslaught, nor adding some tiny damage modifier with some arbitrary prereq that is rarely met in a practical situation. I mean the weapon skills straight up needs more damage.
Power necro's are big on power stacking and vuln stacking. But even running Hoelbrak Runes with Might sigils reaper stuggles to stack vuln in this cleanse heavy meta, and can only reach 25 might by spamming shroud 1. Meanwhile Holosmith is running around with perma 25 might all the time, and able to instantly drown people in vulnerability just by uses Proton Forge skills.
And looking at the Amulets ArenaNet is planning on adding to sPvP, it's only going to get worse. Anet seems bent on adding more and more damage, and the more damage is in the meta, the weaker and weaker shroud becomes as a defensive.
Sanity is for the weak minded
