Recommending to create a training ground to help prepare for SE WoE.
Perhaps an NPC like the MVP room where you can rent an SE Castle to test the following:
- Using flags
- Rebuilding stones
- Rebuilding barricades
My recommendation for the SE castle options would be Vidblainn & Horn which are the two active castles. This makes the most sense and most relevant for training purposes.
Similar to the MVP Room npc, you can rent the castle for your Guild.
Having this training environment would help guilds get comfortable with using flags, rebuilding stones & barricades which improve everyones overall mechanics.
