I am level 25 on BB right now. As a Shaman. I am still learning enchantments because I didn't realize you need some special currency just to save them. So I lost the one I liked and have to go find it again.
Enchantment Altars only being in COMPLETELY RETARDED places does annoy the shit out of me. I think the system is cool and yes it does add flavor that the altars are only in the Ruins of Dalaran (the only one I know for certain is static). It's like the Moonwell cooldown for Horde except 10x more gay because everyone has to interact with it and not just master tailors.
Its a core system of your game. It should be available in every Capital city.
Collections (saving them) is a trap don't do it.
You only need to apply an enchant once, you don't need to save it to your collection. The only reason you would need to save it, is if you want to swap it out for a different enchant in that slot. You may think you'll be doing this all the time but you will not.
Saving them costs you thousands/tens of thousands of runes and applying them costs you thousands of runes so swapping around enchants like that costs you hundreds of thousands of runes.
All enchants are free from the world and can be applied for free without an altar, as long as you explore and find them (or literally just look up their locations on discord), most if not all enchants drop from level appropriate zones where that slot unlocks anyway.
Nearly every single enchant is designed for a specific playstyle/build, whether that is tanking vs healing vs dps or on DPS classes most enchants are designed for a specific talent tree (demo vs affliction or bm vs mm vs survival on hunters, etc)
So basically there's really not very many reasons at all that you would want to swap your enchants, thus there is virtually no reason to save them.
if you want to have different builds, you can unlock talent/enchant specializations (ie dual specs) and you can have unique enchants for each build. You can also loot enchants on any character they are realm bound, so you can easily just go loot the enchant on another character.
There is really almost no reason at all to ever save an enchant thus no reason to ever need to interact with an altar.
People are playing this like they do A52, where enchants can be used on any class (since it's classless), so they pokemon it "gotta collect them all" in case they want to use it on some new build thing. You can't do that here. All enchants here are not only class locked but really, spec locked. Even if you wanted to play like 6 different rogue characters each one of them can go loot the enchant for themselves from the world for free, you still have no reason to save to your collection.
Also they are just sitting at altars playing the lotto rerolling enchants trying to find the rares instead of going out and exploring, spending tens if not hundreds of thousands of runes trying to find a specific enchant. again it's a trap and waste of runes, just leave the capital and the enchant system on this server is 100% free and convenient, you never need to touch an altar to play.
