When will the next refining buffs come ;_;

So many units who weren't even good during the game's launch are now completely outclassed due to powercreep. For instance, look at poor M corrin, who was already underwhelming with yato providing +4 spd when attacking, but now Seigbert comes along who doesn't even have a legendary weapon lorewise and completely outclasses him with +4 atk and spd on his weapon. I would say the same for Eliwood, but at the very least he can upgrade to blazing durandal which is still good. Speaking of which, look at his son Roy. Our boy. He's been bad since day 1 and only gotten worse since then. His weapon is outclassed by a freaking forged silver sword. Both are 16mt, but binding blade only gets the +2def/res boost while being attacked while a silver sword can provide the same quantity of either +4 def or +4res but always, not just when attacked. And once again, someone similar, aka Julia had a similar powercreep problem, but she can also upgrade Naga to Divine Naga while Roy is left with nothing. And don't even get me started on Lloyd and his regal blade, or Valter's cursed Lance. And how does Ephraim get an upgrade to seigmund while eirika is just abandoned? Their weapons literally do the same thing. As you can see, I try my best to make my Roy work cuz I like him a lot, but please for the love of God IS please give the low tier characters the buffs they need. How are you gonna let a forged silver sword beat out legendary weapons?
