TR can be a tricky one. You can't buy the adv from merchant and requires 4 players. However in a guild maybe. Ask around see if the more experienced players have the adv sitting, dusty in their star. Get 4 players who want to run it at Easter and bingo. Can be done with only using fast gens and only takes 5 attacks each. 1 of the group could start a 2nd adv while the group are hitting the first, they could have a 2nd attack setup waiting to send as soon as the 1st is complete. Use the wiki guide for camp numbers but the attack numbers work like this:
Nus 98r 5es - 66-73-98
Nus 48r 21b 96xb - 31-35-48r 8-15-21b
Nus 20r 60b 85xb - 20r 29-37-60b
Nus 50b - 50b
MG 117r 1es 152xb - 92-108-117
Load Nus and MG for 1st attack then need 68r and 131b extra bringing
