So I hit Tier 3 recently and though I can solo it somewhat, it's slow and tedious. But every time I try to join a party for Tier 3 down it always tells me that there isn't one available. Cmon, where are all the Tier 3 parties?

And for that matter, where are all the Tier 2 players? Every time I start a party for Tier 2, nobody ever joins. It's disheartening.

Also, I see players with 90k+ energy and full 5* equipment still running Tier 1 and Tier 2. Now, if Tier 3 rewards better mats and way more crowns then T1 or T2, why don't those players just run T3 exclusively outside of helping other players?
