TERA is already way too expensive to play these days and the last thing I am going to do is spend a ton of money on character bound mounts. End of story.
Tera will be expensive if you want to keep up with the whales or if you want that new mount with the unfair buffs and that super glowy cosmetic right now. But listen... As gearing goes, that will only get you into afking on Highwatch showing your character's glow and nothing else. I mean, by now that's the only thing spending money on gearing will give you, since pvp is pretty dead, unbalanced and not worth even mentioning. And the same stuff may apply to speed running. As for going for gacha mounts and outfits, that only perpetuates the company thinking that gacha sells and they will see no reason to change it, but more reasons to push even more of it down our throats.
So really, keep your money in your bank unless it's for direct buy cosmetics, or to play the broker to get whatever new gacha stuff the whales are selling there (I got me a new bunny mount the other day by selling old stuff from my storage, for example). This is all I can advice anyone out there. I've been on and off this game since 2012 and I'm yet to spend a single dollar on gearing up. But I did buy plenty of shop cosmetics back in the day. Sure, I personally don't need powerful gear because I'm not going for any top dungeons. Those get usually dropped to lower tiers over time, and even moderate gearing will get you into several dungeons if you get tired of the gossamer place. What I feel people should be doing is to try and get together into similar tier groups and grind together. If that's even possible in this day and age.
In the end, all I want is more and better direct purchase options because I'm not rich enough to be spending money on gacha stuff. Much less for gearing up, which history tells us it's an extremely temporary thing.
I'm assuming someone higher up the ladder had the brainstorm "Why are we letting people buy one thing they can use on every character they ever make when we can make them buy one for each of those characters instead?" without considering the more realistic outcome being people buying nothing at all.
This is my train of thought as well, as it has been the choice I myself picked.
