Aegon R5 for Labyrinth?

Bhop

Just did initial easy path labyrinth clear with Aegon R4 110 sig. Was tedious but not too bad using, Heimdall, hela, star Lord, Angela synergy. Planning exploration (prob gonna drop Heimdall or Hela for fury 20% attack boost) and debating if R5 is worth resources? Have 2 t5b and 6 t2a with initial map 6.1 and 6.2 clears done as well. Let me know why please!
