we are reseting the TW Map when we see the map is totlal yout of challenges.
What you mean about PWI is due to one single Reason, theres 1 guild with a lot of players absed on cash, that yes removes all the fun in TW's in that game but we do not face that problem here, we have a balanced server or at least we try to keep it balanced, so the TW's aint that bad.
We see at the moment around 11 guilds still fighting in TW, thats not good? for me it is, i came from a PWI server where was every weekend 2 guilds fighting, thats not fun at all...
So don't worry we have the TW Map under constant check ups.
