Cleared all coils (when recent); A1S; A2S and all EX primals (when recent) without any voice programme. My static started using TS lately it can be nice help to call out the mechanics in A3S but idk been last phase before without and often it is more used for joking and distraction
Can be nice help to coordinate a "I don' have swift up" or when the SMN takes over the raise or to improvise if things go wrong but if team works and has same progress curve doesn't make a difference that much imho but can shorten progression surely.
