If you wanted the items in the lockboxes you'd be spending more than the $15 a month, which goes towards developing real content vs cheap temporary content with the goal of lockbox purchases (why else put even more dev power behind the temporary content rather than permanent content? because that's how they make the $$$ to sustain the game).
Also (I can speak from experience for Tera at least) every single event that Tera has is based around the lockboxes. Christmas? We've put weapon/armor skins in the lockboxes, along with Alkahest/Enigmatic Scrolls to enchant all your gear with! Try your luck! Halloween? Same deal. St. Patrick's Day? Same deal.
I will say that GW2 does much better than Tera in that respect though. Tera barely does anything other than make some themed items and put them in lockboxes. There really isn't that much content developed for the events. You really only know it's event time because your screen flashes a big overlay message when someone hits the jackpot and gets a rare item from a lockbox.
You're right that in that I haven't tried GW2 in a while though. Mostly because I was starting to get the same vibe and have had enough of that type of development. I don't want every single event in the game to be centered around a few half-hearted pieces of content with a focus on getting items from lockboxes.
It's not like I can unsub though (one positive GW2 has). I'll just wait it out a few more months and see if they change direction or put even more focus on the lockbox stuff. I put so much work into my Warrior (getting most of my legendary stuff, 100% world completion, etc.) that I'd love to come back (I like the art and the feel of the game).
I had thought WildStar was going to outshine GW2 since it's promising real end-game content along with having a similar combat system, but after having played the beta recently the movement/combat/animations/UI/etc. are all just a mess. It's really nowhere near the quality of GW2. If only there was more (permanent/non-event) content.
