Think about it.

You spent 3 months to get your novus weapon, hours farming fates, doing brayflox, killing thousand enemies around Eorzea and get your weapon.
Then, after all your effort, SE choose to remove novus weapon because are powerful and broke the game. What will you feel?

I spent one month and half, people did fates and brayflox farm and i played pvp 4 hours or more each day. Now, all my efforts is not rewarded in frontline because the pvp gear is useless.

Ok, we have wolves' den, but, who will queue again? A new player will go to frontlines so queue will be more long in wolves' den and players focused on pvp are a few compared pve.
