I recently replayed a few missions with a guildmate and found that the Mission Arenas have been updated. They now look much nicer and I really appreciate the effort, but they really need to be beefed up considerably. That is unless the point of the update was to make the arenas very easy and quick to run through.
I don't remember exactly which missions they were but one of them was the Construct/Freeze arena. The updated one is waaaaay easier then a stock clockworks arena.
Anyways, the suggestion is to beef up the newly redone mission arenas because they are very easy and quick (compared to normal clockworks arenas of equal depth).
I agree. Although aesthetically pleasing, Rise or Fall became very... unchallenging. The payout was also reduced in the treasure rooms. I would like a buff to arenas to their former glory.
