It seems like the difficulty of the ships battles in phase 3 and 4 were okay. Maybe a little bit on the too easy side. But the jump from Phase 4 to Phase 5 was significant and now it's an all or nothing situation for TP which will cost stars. I can't imagine the difficult for Phase 6 of this TB and may not even get the chance to experience it. My ships aren't maxed but I don't believe they're bad either. 7 star ships with G9+, fully modded pilots.
CG, please spend some more time on this for the next TB. Either scale the difficulty more appropriately or give us waves back.
