Sorry but there are many more tamers than people that care about factions. Factions aren't barely existant because they are bugged.
If EA actually bothered to spend their time fixing existing bugs and design issues,
They are barely existant because no one cares about them to begin with. Felucca is already dead and even fewer players play factions, so adding something like greater dragons interests a huge segment of the population and working with factions interests a very small part of the population. As a developer its better to keep the majority happy at the expense of the minority.
Uhhh, no. Factions were huge, but the bugs (as stated) and other issues made it not so fun.
Where'd you get your info for there being more tamers than people that want to play factions?
Since when are tamers the majority? I'm sure there are more people out there screaming to fix thief nerfs than there are tamers looking for greater dragons.
