I hope there's a LOCK button option on all runes so that we can protect our runes from being traded or forge mistakes...
When you making trade, it's written which rune belongs to which bg. For forging it also shows if that rune is in bg.
yeah I know but it's still much better if you made a mistake and it will prompt that this rune is locked you need to unlock it first before doing something... You FEEL ME?
I think the current warning is handholding enough. If you cant take the extra second to read if a rune is included in a bg you can concider it a tax for being lazy.
