Relic Delta - Constructive Feedback

I think that you are too generous to CG. Your analysis is correct, but raids and TB (especially TB Ops missions) already massively prioritize bringing toons up to specific relic tiers. As a result, I don't think you've considered that the incentives that already exist might be sufficient, 

If they are (and I think they are) then being forced to bring all of your most active teams to r9 means being forced to neglect other squads. 

We are already pushed heavily towards certain teams. If we bring those teams to r5 and r6 and still can't use them in, say, Conquest s5 or as counters in TW, then that investment is largely wasted. 

I understand that CG wants me to push more toons to higher relics, but I'm going as fast as Signal Data allows me, and others in my guild are gated by Droid Brains AND Signal Data. 

As the OP says, this encourages accounts to build tall, by ignoring much of their roster to make sure as many resources as possible are available for a few, very strong squads, which is precisely at odds with the incentives in TB and CQ. 

But also it simply kills theory crafting. As I've explained elsewhere, SW:ANH relied on underpowered characters going up against an overpowered Empire and winning because they had the right plan and the right personnel to exploit the one vulnerability the powerful Empire had. 

That's theorycrafting. Another team is stronger, but you win by carefully selecting the abilities you want to use to exploit the stronger teams remaining weaknesses. Relic Delta would armour over those remaining weaknesses and make counters impossible to use without matching relic levels. This essentially demands the Rebels build their own Death Star to fight the Imperial Death Star. 

Relic Delta stands athwart the spirit of Star Wars while also diminishing the players' role in determining success. 

I don't want my brain removed from the equation. I want my brain engaged in the games I play. And I want the spirit of Star Wars to live on in this game. Therefore, I condemn the entire idea of Relic Delta and seek not to moderate it as the OP does, but to simultaneously drown it and incinerate it in the lava rivers of Malachor.
