This thread is just hilarious, people actually think that there is even the slightest chance that getting a completely disporportional amount of xp compared to anything else in the game is intended(you can call it exploit or wtv the hell you want semantics don't really matter).
I personally don't care, i don't do it as i fail to see the entertainment in it(or in any fate grouping as it is right now).

Oh and by the way, any form of fate grouping in its current state is an exploit, the producer himself has stated that the FATES are not scaling properly right now and that they're just letting people have fun with it...

Again i couldn't care less, i don't see the fun in skipping content just to come into the game after 1 month and whine that there's not enough content.
