Do NOT buy GW2 on Steam.
The Steam bundle that includes all three expansions costs $60. The GW2 website bundle that includes all three expansions is $50 AND includes a shared inventory slot and a max level boost.
The steam $100 bundle includes all three expansions and the living world (patch content). The GW2 website $100 ultimate collection gives you all GW2 expansions, including everything in the EoD deluxe edition, and 4,000 gems (which is enough to buy all Living World stuff). The EoD deluxe edition notable includes an inventory slot, a character slot, an identity repair kit, 2 mount skins, and 4,000 gems (which you can use to buy all Living World episodes). Also includes a max level boost.
Also, the two steam bundles in the ingame store are a rip off. Don't buy them. Anet is blatantly hoping to prey on noobs who don't know any better there.
