To put it in perspective:
Heart of Thorns (originally $50): 10 maps
4 maps base + 6 added in LS3
$5 per map
Path of Fire (originally $30): 14(+2) maps
5 maps base + 6 added in LS4 + 3(+2 map expansions) added in IBS
$1.87 - $2.14 per map, depending how you count it
End of Dragons (originally $30): 5(+1) maps
4 maps base + 1(+1 map expansion) added next update
$5 - $6 per map, depending how you count it
Next expansion (slightly reduced price guess: $20): 3(+1) maps
2 maps base + 1(+1 map expansion)
$5 - $6.66, depending how you count it
And here's "new player" pricing if you missed Living World:
HoT + PoF ($50): $5.55 per map
LS3 (1200 gems: $15): $2.50 per map
LS4 (1200 gems: $15): $2.50 per map
IBS (1200 gems: $15): $3 - $5 per map
EoD ($30): $7.50 per map: $5 - $6 per map
Next Expansion ($20): $5 - $6.66 per map
Honestly I wrote these out because it seemed like we were getting a bad deal just reading the blog post. But after looking at the math it seems that PoF was extremely underpriced at the time it was released, and new players will miss out on the roughly half-price content from Living World.
