Tetris isn't just "max single thing" and nothing else. There's a lot of nuance to it. It'd just spit out a gearset that leaves a person otherwise bad. High damage per hit, accuracy so low it never hits or so glass mobs don't even have to hit them to kill the player, etc.
I soloed for several years after my guild buddies all stopped playing. So regardless of what l read on line, and thinking l’ve read quite a bit, my test was in a real dungeon that my toon runs regularly and l can gauge a real difference.
I found, since l’ve only run healing melee toons so far, Pally, Ranger, that it’s a combo of self healing and DPS that gets you through.
I have been a fan of Fellblade from day 1, cuz l like long swords and pretty sure they were my go to when l played PnP D&D. Before the crazy changes that brought all the high end swords down to earth, no one seemed to pay much attention to Fellblade, but l could never ignore its crit profile so kept using it.
Then everything changed and it became the Go to LS on paper. Read several posts about it being better than Soulrazor because of its better crit profile now that all LS’s had fairly equal dmg.
When l finally got my hand on Soulrazor (yes l had to see for myself) took off Fellblade and wasn’t fare comparo because l was now also down 15% dbl strike, it wasn’t close. Running through WPM, l consistently dropped something like 3-4min on R2 and lMS was finally able to beat it on R3 solo.
So whoever was figuring things on paper was obviously leaving a lot out.
Bottom line is that l totally agree, gear Tetris is all inclusive. Also why l went with Salt 5 piece, right when l was about to spread out and farm some 2 and 3 piece sets to try to fill in missing PRR/ MRR etc. l found the Salt 5 piece gave me all the critical stats l was looking for plus the set bonus which l still think is one of the more significant set bonuses in the game if your already wearing 3 piece PotF.
