The balance was completely destroyed.
Let's start, as usual, with PVP. Relic Delta. It was introduced out of habit during TW and GAC, without giving us the opportunity to finish these two modes without Relic Delta.
Freezing. Why test anything? Who are players? Only testers play SWGOH. Let them suffer and lose because of freezing – we'll fix it later.
Leveling. The developers left us no choice about what to level. In their update, they told us: "Forget about those who haven't been transferred to Relic yet. After all, you'll be spending energy and raid currency on leveling Relics." Raid currency in MK2 is needed to obtain Relic materials, but it's also needed to level up to G13.
New characters. As the developers promise, with active participation, we'll get a character in G12. But until G13, we'll have to level up characters with MK2 raid currency, which is needed to level up relics.
R10. I haven't even touched on ship speed yet, which won't get +1 speed, but much more. Which will also get additional speed later, at R11+.
