Yeah... that wouldn't actually make any difference. See, Captain D here has very specific expectations and notions. For example, defenders who use anything other than heals or buffs are "wrong". Tankers who press any key that isn't Taunt don't know how to play. Controllers = nope. Dominators are worse controllers. Et cetera. Consequently, his recruitment qualifications tend to dissuade some players, disallow others, and extend the process unnecessarily.
When he finally gets rolling, his requirements have historically driven players to depart ASAP, thus a delay as he stops to recruit replacements, who will be, as noted above, have to meet certain qualifications, or are booted shortly after joining if they're not played the way he wants them to be played, or they hightail it when they realize what they've gotten themselves into, creating further delays.
He's also restricts himself to lower level play, for various (and hilarious) reasons, so he has a limited target set, and he only runs certain arcs at those levels, so he's competing against the DFB/TF-to-20 crowd. And the AE crowd. He's basically dredging the bottom of the barrel at that point, only getting people who want a badge for something he's running or who have just started playing and are only joining his team because his announcement was the first they saw.
In a nutshell, he's spent five years training people to avoid him and is reliant on newbs for teams. And we ain't exactly overflowing with those on any shard.
