I wouldn't class myself as a pvp type of person, but I've been taking part in pvp content, and usually having a bit of fun doing it since its release.
Of course the biggest draw for me wasn't the exhilaration of battle and stomping people. (It might sound silly, but I tend to feel bad when I have to kill somebody, especially if the team is losing, thus i play healer!) The draw was unique glamour and mounts, which i assume is the case for most people.
The problem i'm having is twofold and perhaps subjective. I'm unable most days of the week in actually joining frontlines content, specifically since "Shatter" has been released, regardless of whether i queue with roulette or no. Second, in my personal experience the win rate for Twin Adders has been absolutely atrocious. An example would be that i'd been trying desperately to get the Field Commanders set from "Seize" several times a day throughout its entire content life-cycle, and to check my achievements to see that i'd only ever won 25 times is really disheartening.
One might say that i'm just bad at pvp and letting my team down, but i'd disagree! I take pride in my ability as a healer in both pvp and pve content, and i always put my all into every game. I'd managed to get the cute airship mount from the "Feast" relatively quickly! But when I compare that experience alongside twin adders in frontlines, it's a worlds difference. Of course variables such as content objective and luck of player skill levels are also always at play.
My point is, I don't think i'll live to see myself get the regular ADS mount, let alone the white one from shatter, so SE can you at least let me pay you for one? All i want to do is bounce around on a future ball, even if may be mud green looking.
------Edit: To make clear, i'm not asking for these specific achievement rewards to be purchasable but an alternative version/reskin able to be purchasable or obtained through other means. A la Bennu/zu mount, parade-chocobo/white-fat chocobo.
