Yes, you can play this game for free it is just so time consuming to do so that most people will
pay for content instead of grinding the favor system for TP to pay for content.
Let me crunch some numbers so you know what I say is true.
Currently there are 78 free to play quests in the game.These quests provide 907 favor. That
is enough favor to unlock the server favor up to the 4th tier which =150 TP. Do this on every server and you get a total
of 900TP
Now Free quests will also give enough to earn you 225 TP with character favor rewards. A f2p
player gets 2 character slots on each server if you do this on every server you will get 2700 TP
Combine that with the 900 we totaled earlier and you get 3600 TP, from grinding 100% free content.
You can then use those TP to purchase adventure packs which you can then grind to earn more points.
Then of course there is the option of rerolling which can provide more TP which will only be limited
by your willingness to keep rerolling.
