1 Tip for your Staggered Team. Anytime I get a character thats out of Sync I just tag boost him myself. Ex. Drive main character ungrouped with the other four higher level grouped behind him. Go to world and either ST or AoE target mobs that are between Your level and teams and you can kill all day with basically zero downtime until you catch him up. You get full xp per kill and are going atleast 5x faster but actually more because of no downtime
