The one I'm against the most is the Rewards option (specially the participation one).
Why?: its easy to abuse, here's how (one method)-
Make a rouge/sin (or stalker/sinx) or get a hide clip.
Get blue potions.
Go to prontera castle, enter, go straight north of the warp.
Hide.
Sp gets low, unhide (unless youre a stalker and are in chase walk).
Use pot, hide again.
I'm against the time based one too (as well as the other) for a second reason:
Quote:Woe is about War. It's not about 'oh I tried so i get something.
If you win you get the castle along with the rewards of the castle, if you lose you know you need to get better, and hopefully you will do better next time.
