for boss raid events only:
I don't know if I'm crazy, but this has happened enough to me over the last 3 months I'm starting to wonder...
I have a healthy list of T1 allies. Many have been long term allies, and others have been in and out. Each event, I'm normally able to add 3-5 new faces (each event I tend to lose 3-5 as well). This event, Broadman312 and CannibusPrime gratefully took me on board (thank you btw). And I've gotta say, all event it felt like a 50/50 chance the MM and Lv8 seeds I saw were from one of them. My queue was 4/6 from either one of them more than once. I know my other allies were equally active, since they placed just as high in the event (GoC, Hypno, Masa, ARO, RyGuy, etc) but I saw a nominal amount from them.
A few events back, I noticed the same with Patorikku. he was my new friend and I got tons. A few before that it was Hypno., before that Toumpano. when I first met Ry-guy and GoC I got tons from them.
If a T1 has consolidated (dropped me!) and then been generous enough to re-add me after the event, I often see an uptake from them also. I've noticed this with Thunderclonus mostly since we're on/off the most.
So long story short: call me crazy, but I'm beginning to think that the game creates a "seeding pipeline" with your newer allies over your older ones.
Lesson for T2? : drop your top allies and re-add them! LOL (seriously, don't do that).
anyhow, just thought I'd share a random thought in case anyone else out there thinks they're as crazy as me. I suppose gaming times that are the same between me and said ally could create this effect, but I don't think timezones,etc explains enough of this. certainly my previous "pipeline allies" haven't changed their timezone since!
I doubt the T1 crowd would notice these dynamics given their gameplay is different to T2. (not to mention these dyamics are probably figments of my creative imagination).
