I'm sticking with the six month plan for now, discount plus getting all the crowns at once, when my subscription renews will have everything I want from the crown store till more is added with a little left over.

Most likely I will unsub. The main reason is that I solely play TESO as a single player ES game (solo questing, exploring).
On this aspect no new content has been released in its first year. We did receive a huge mechanic update (champion system), some stuff that should be there at releas (dye system) and a big overhaul of dungeons to get more people to group.

Zenimax has shown us a lot of teasers of new content, however there is still no timeline of their release. This has brought back very bad memories of FunCom's Age of Conan. And as Zenimax has stated to publish the first DLC after the Console release that means we have quite some months to wait for anything new.

Besides new content, I still haven't seen all the already existing quests. Still leveling my first toon in the veteran ranks and also started some new ones to see the various classes.

Last but not least: the world is for me a lot less alive than GW2. The NPC's walk around a lot more in that game; quests (events) happen more natural and people join in to bring them to a good end.

Consequently I'm currently playing both GW2 and TESO to figure out which one fits me better.
