I feel like some people overcomplicate getting to tables. It's pretty straight-forward. Levitate. Get real high. Follow the map, go through the entrance areas. Here's a clip of me doing it: https://www.twitch.tv/videos/408439433 Do this.
Never knew you could lev over the castles. thanks edit: One thing though - in the TBL raid you would have to have everyone swim out through the lava tunnel to get back to where you started, wouldnt you? Not sure thats easier than killing through the castle.
You only need enough to CoH and then drop a guild standard. Also as a note: there's invisible walls and you'll get stuck. You need to do exactly this.
Heh, i can guarantee our guild would have more trouble doing that than killing the 12 or so mobs that are any problem getting by.
The lava in the raid instance does a significant higher amount of damage per tick. Also, in the interest of both sides, I present How To Train the Tables in Doomfire Like a Pro: https://gfycat.com/eachscarcegnat
