As tempting as it is to say I told you so or to fill this entire post of me hahaha'ing, I won't. It is deeply satisfying that zos has shown its true colors to it's supporters though.
With the announcement that eso is going b2p with a cash shop, its only a matter of time before it goes ftp. Eso is in my opinion is copying lord of the rings online's business model. how lotro's model works is like this.
1. completely FTP. you can create a character and roam middle earth free of charge but with restrictions. can't send gold in mail, only get to create 3 characters and are limited to certain classes because some are locked until purchased, and every town you run to has npc quest givers with turbine icons above their head indicating you have not purchased that quest pack and are unable to do the quests.
2. PTW cash shop. all quest packs and expansions are available for purchase including dungeons, raids and skirmishes. every advancement item is also available for purchase. i.e. potions, food, crafting material, dyes, passives, traits, xp boosts, mounts etc etc. to boost sales lotro's shop will have "specials" i.e 50% off items.
3. you have an option to go "VIP" which means you pay a monthly sub and get all access to all content as long as your sub is still active and you also get 500 turbine points to spend in the store a month. However if your sub runs out you will not be able to continue with vip material until sub resumes or content is independently purchased.
whats all this mean? if eso follows this model sometime this year you will see similar circumstances. you will be able to buy tempers giving you full legendary gear and be able to buy fully buffed mounts, tri-pots, purple food, etc straight from the store.
Really the sky's the limit on what can be offered.
There will be grind spots going 24 hours a day for non paying players in order to get to max level (better hope you don't have quests required in that zone).
gold sellers will come back because they can just create infinite free accounts.
I can make this list go on and on but you get the idea.
