And mine look like this after upgrading only a single epic weapon, and only commons or rares otherwise.
Thats 3 + 5.5 + 29.5 more epic ingots for forging up every single other one (which I’m not even done with yet), 36 that I spent, bringing my grand total to 136 Epic Ingots or equivalent found, ever, compared to 223 Legendary, a disparity which will widen immensely over time due to delve loot.
But also consider you only need about 1600 epic ingots total to finish upgrading all epic weapons with not too many more likely to be added while you need over 4400 legendary ingots with 2 weapons coming in at this rarity every 3 weeks, another per faction so another one per month, each of them taking 45 ingots. PvP drops and chest drops heavily favor lower rarity stuff that you are more likely to be “done” with. Fully upgrading every epic weapon may be a bigger bottleneck long term now, but all those common through ultra-rare ingots should to go somewhere, and the path from common through ultra-rare to epic is ten times less ludicrous than the path from common through ultra-rare to epic.
On this, I think everything would balance out nicely if they just upped the minimum rarity of the random ingots you can get from Renown from common to Rare, or maybe even Ultra-Rare or so so that everything is nice and rounded. Or, you know, leave the imbalance where it is so they can sell Weapon Upgrade packs.
