Capital Games TeamCG_Meathead - I can understand that you guys underestimated the sheer resourcefulness and cooperative team-working of the players to problem solve this raid into the smaller sized than expected teams.
However, by only commenting now you have already left it to late to change things without some sort of outside the box thinking
To generate the Relic materials to take R7 characters to R8 and R9 - the only real source in the game is raid rewards.
I and a lot of fellow players had hoarded the relic resources for months and then spent them to get e.g. a 3 man Jedi Master Mace team at R9 and/or a R9 Tarkin/Clones team.
To regenerate those relic mats now (at a much reduced return) will take months - with the lack of unbalanced/non-fully viable teams simply multiplying the length of time this will take.
I accept your right to change the logic behind which teams will need more members. I and most players may disagree with it - but you have every right to do it
BUT - if you do make these changes - you MUST let us be able to undo how we have applied our relic mats to allow us to have made a more informed choice.
