Is there a limit to gem/gold conversion?
The more gold you buy with gems the less gold you get.
You can only exchange for Gems or Gold if such resources are available in the pool.
As for GW1 ‘expansions’, other than EotN, I believe the subsequent Campaigns cost as much as the original Campaign. At least, they did for me. =)
From early posts from dev John Smith, the exchange was founded with both a fix amount of gems and gold. A gigantic amount of gems relative to gold and it’s this ratio that sets the exchange rates we see. As players buy gems with gold the exchange gets more gold and has less gems making the gems remaining worth more gold. When gems are sold to the exchange the reverse is true. But since many more gems are bought from than sold to the exchange the amount of gold is steadily increasing while gems are decreasing.
This means that as the mount of gems in the exchange run low, yes the exchange can run out of gems, the rate will go higher and faster unless the gems for gold counters it.
The true purpose of the exchange is to fund the gem to gold side with the gold coming in from the gold to gem side, so there’s a way for players to “buy” gold while at the same time not introducing new gold into the game’s economy. At the end of the day the purpose of the Gem Store is to be a source of income for ANet and you can’t do that if players always have enough gems from gold conversion for all their wants.
Also since there are no items that affect a players stats on a permanent basis, there is no Pay to Win. Cosmetic and convenience items are not pay to win. Nobody considered that was the case with the cash shop in the first Guild Wars.
