In generell armor mods on focus are "useless". When u want to defend have a defense set ( shield 🛡 and weapon ⚔ with a +5ar or +30hp mod) and when u want to cast you switch to a 40/40set (or 20/20 if none anttribute skills) only other really played option is a high energy set Wich would be +15energy-1regen mod with a 20%er or maybe 10%er or 30hp. Note that a high energy set allrdy is a rather rare used version and value of those are significantly lower(also the 10/10 offhand and wands) even tho it's a real playable set for some build, situations and PvP.
So now back to your focus. It's q11, it has an armor mod and is a basic skin. Wich leads for me to only 1 conclusion - - > merch.
Feel free to wait for more opinions ofc
Well, the req doesn't really mean anything, we all know it but pretend its important. Who buys a BDS q9 and then only uses 9 in that attribute? lol NOBODY.
As for having a defensive set, ST renders it pointless in all but a few parts of the game. And even in most of those small cases, kiting is better than having a shield. On top of that, heroteam builds also run defensive options on top of ST, n/mo prot for example, so again, defensive sets don't make a difference. Solo farmers might need em, but nobody else does.
And yeah, high energy sets are generally pointless too because the majority of players run BiP meta.
And the suggestion to run a 40/40 ummm have you seen a necro AP build before? Theres generally only 2 curses as a standard, so 40/40 is absolutely pointless. 20/20 is an option, but having compressed mods into one item is pretty ideal for a lot of players.
