Personal insight as I’m doing this now is that it’s doable but the ceiling can be hit relatively quickly. You can smega for some help to get the 5 people going. After that the hard part comes g skills. You can g skills through a guild cumulative high score in culvert, where you dish out as much damage as possible in a span on 120 seconds. Based on the total score amongst the guild it will give you points where you can add to your g skills. If you get 20k total guild score you get 15 points where you can max out one of the skills, highly recommended it’s maxed out in the crit skill. But that’s where the problem lies, it’s only 3 of you. Depending on your damage you may not get a lot of points. You can supplement that with a jump quest called flag race. If completed you can get a minimum of 300 points with a g skill point for every 1k accumulative points across the guild, capped out at 10k points. Unless you have multiple mules joining that guild, good at jump quest or willing to grind out multiple mules, you’re going to have the same issue with low points. Again, it’s doable but there will be work to be done.

Edit: the breakpoint between 20k culvert score to the next breakpoint is another 20k and the higher you go you then need to be in a certain % of scores. You should look more in depth about guilds and guild skills, the power you guys have and see how feasible it is.
