Look, I don’t think this is something that would cause a problem for anyone, but the thing is, some people (like me) simply didn’t read what those Rokas Recipes gave and took the general path (Plate Armor for Wizard for HP), now I’m level 230 Sorc/Warlock and those +10 INT are the best thing I could wish for an Armor.
The point: there is now way I can get that armor on my Warlock right now and by no means would I reroll him since this is the only missing point. Also since you can only use 1 Top Armor each time there’s no reason why having more than one of those would affect balance at all.
This is a simple modification that can make people who made a big mistake (in some cases) very happy, it’s an equipment you get very early in the game so there’s no way I could know about it.
