First of all, I think the stream today has been great; amazing job/chemistry/humor by the team.
But as far as the BG changes, the big three are pretty interesting, and I think two of them are easy winners.
(1) shuffle signet: so it sounds like the goal is to change this shuffle system so that when you reshuffle, you keep your original options, and just get additional options on top of that. Seems like a W update there; looking forward to it.
(2) little leagues: so this sounds like a "safe space" for low progression players to play BG without being victimized by lazy/predatory high accounts hanging out in the lower tiers. Again, seems like a W update there.
(3) whitelist/blacklist: Ok, this one I think can go good or bad depending on how it's implemented. Basically, it sounds like this will only apply to GC, and every season Kabam will decide which specific champs cannot be banned and which champs cannot be even in your deck.
I can see how this might be a good thing for creating variety.
But then again: if the unbannable champs will be the P2W ones like Dark Phoenix, Red Guardian, Lumatrix, Torch, etc.
And then the banned champs will be old staples that most modest players have, like Bullseye, Titania, Juggs, etc.
I can see this being another pain point for the normal players and advantage for the big spenders.
But again, that's speculative, but based on the direction so far, it's a real concern for me. We shall see...
