Guild Wars 2

I can not speak for anybody else but in my opinion the expansion broke more than it fixed and if you are mostly in for the story like me you are going to be severely disappointed not to mention the dull XP grinding for masteries. On the other hand if you are interested in raids and map wide events the expansion is probably right up your ally.

While the price point does not bother me much I think that there is absolutely no incentive to pre-order anytime soon as there is not even a release date announced yet.
Even the closed beta does not have any dates set as of now and for all I know HoT could release in spring 2016.

Furthermore there is not much information available regarding the content of HoT and, I have to say, it does not look like it is much from what I have seen until now.
Three new areas, guild halls and a bunch of specializations sound like a content patch and not like a proper expansion to me, especially when compared to the GW1 expansions.

The last two medium armor sets that where added to the game(Carapace & Glorious Armor) do not look like trench coats so there is reason to hope that HoT will offer a more varied collection of medium armor sets.
