In CoX, the vast majority of the badges you could get did nothing for you except look nice. They ALL gave you a subtitle like "Isolator" or "Rocket Man" but apart from that, only certain specific ones led to Accolade unlocks, which generally gave you either a long-recharge prestige power, like the Crey CBX-9, or some kind of passive thing, like 5% more hit points, etc.
I generally only cared about the accolades, for the most part, and even then mostly the "passive stat buff" ones. I eventually got around to defeating enough Carnie illusions to get the Archmage accolade, but it was low priority due to being a kind of "meh" prestige power (in my mind, especially as compared to having 5% more total endo).
That said, every little bit helps.
In GW2 a lot of the achievements you can get don't actually give you a publicly wearable "title" like the badges in CoX did. I'm not sure if we want to go that route, but if we did, I would suggest that maybe having a special badge title for every different level of "defeated 100 Crey" or "took 10,000 damage" doesn't need to grant its own unique, publicly displayable character title. Maybe you just track those badges you've unlocked in your own badge window, but don't give them the title perk. Then the "defeated 100 Tsoo Sorcerors" badge is just that, and doesn't need a cool name for when you choose to "wear" it, because it wouldn't be a "wearable" badge.
Okay, that was all preliminary to what my main point here, specifically more actually useful powers/bonuses unlocked from getting badges.
What if completing all of the "Aether Pirate related" defeat badges, i.e. getting the badge for 100, then 500, then 1000 generic AP defeats, plus the one for defeating X bosses, etc (all of which would be non-title-bearing in my mind) resulted in a special (title-bearing) accolade-like badge which not only has a title associated with it (like "Aether Cop" or something) but also granted an accolade-like prestige power? And for the power, I'm thinking something faction-specific and very minor. Like a super-long recharge, AP-themed temp power, or a passive power called "Aether Pirate Expert" that grants maybe +1% damage or +1% defense versus the faction in question etc.
That way, people like me, who only ever cared about the badges that gave you some tangible benefit, or MAYBE occasionally would do a badge to get the cool title, would have more badges to want to get.
Just an idea. I mean, it's basically what CoX had, but like MORE of that, maybe to the point where every "non-title bearing" badge you could get might eventually be part of a larger group which would unlock something tangible later. Some of the "low level" badges (i.e. the ones that don't grant titles of their own) could be included in multiple different "greater badge"unlocks (i.e. with title and prestige power). So like if you defeat 1000 Trolls you might get credit toward the eventual Troll accolade, but you might also need that badge for the "Gang Buster" accolade, which requires different badges from defeating different "street gang" type villains.
Oh, and all such granted powers would be, like the Crey CBX-9, non-augmentable.
