GM was in the wrong for Raid 2 if he said it like that. He was just surprised since no one else was able to clear it.
Raid 3 was meant for all 8 players to be attacking and playing the full map. In ur pic there was 3 people with 0 points, 2 with points, and 3 others not there. It can also help if you use more TA, rather than TD. This is why it is even more silly on making it a 4p map.
@ pen:
Counter is too slow, limited amounts of pushing, digi maybe, Using skills / combo is better than jump atk spam. Method atm is TD patch.
