When do I shift realms

[chilly oak]

Been pulling blue from the start, day 7 tomorrow, planning to use the selector on e1 jenkin. When do I know when to shift to other realms, e2 Goliath or +4 sanga. Also to which realm is better after this caro or chaos

I think it better to wait for the anni event and see what happen bro maybe the meta gonna change when first year anni unit is out
