I would like to add a few questions/things that came to me.
We need to make sure the draw of lots for matches is random. You might have already though about this but there was no info on how you will decide who plays who(brackets etc).
I will try and convince the core raiding team in Midian to come as well, but we have no pvp gear(relics apart lol) and will get facerolled so luck is important in draw(as I expect not all teams to be full PVP teams). hopefull others will follow in PVE gear and we can all have some fun.
There needs to be cascading prizes, and I think they need to be mentioned asap to get more people in and need to be adhered to. I know you had a successful event but then due to wahtever reason, the prize was revoked at the end. even if its for fun, a prize will keep people motivated beyond the fun and get some proper competition going. I know my team has no chance of winning, but still
