I'm definitely interested in such a group, and, yeah, I think we have many people who would be interested and happy to work on developing this.
TBH, I like seeing people try out different stuff, then making it fit together. We can look to have a group that wins against greater numbers without having to go all GvG on it. Those builds are certainly central to the meta for a good reason, but I'd also like to maybe examine this in terms of role composition.
What roles makes for a well-balanced 5 man? (1) healer/support, (1) support/DD, (1) DD/support, and (2) DDs? Or could it look like (1) healer/support, (1) DD/cc, (3) DDs?
Or, what if we wanted a pure bomb squad? (1) healer/support, (1) condi DD, (3) power DDs?
IMO, in a guild like ours, flexibility in group comps will keep a regular-running, result-focused group together longer than 5 people rolling perfect meta comp and getting immediate results. I've seen firsthand what happens with the latter and, not coincidentally, am the only person from that meta comp who is still in the guild.
